Hey there, wait a minute Mister Postman. Is there value in that factory letter?
The debate over the value of a “factory letter” is one that seems to pop up from time to time in gun forums. So what is the answer?
What Is a Factory Letter?
Model, condition, finish, grips, engraving, where it was shipped, to whom it was shipped, and serial number range are all considered in determining an old gun’s value. A letter can help answer some of those questions.
In Rock Island Auction Company’s recently completed Premier Auction, factory letters from a number of gun manufacturers like Colt, Ruger, Smith & Wesson, and Browning were provided. Buffalo Bill Center of the West has records for a number of long gun makers like Winchester, Marlin, and Ithaca, and many of those factory letters were also provided at auction. Private authenticators like John Kopec also lend their expertise with documentation.

What Information Is in a Factory Letter?
Those who don’t see the value likely aren’t concerned about the collectability of a gun or don’t want to get bad news. Those who do get letters see the value of an antique gun as a piece of history and want to know its heritage. How did it leave the factory and where did it go?
The cost of a letter — ranging from $10 to $350 — is often seen as adding value to an already valuable gun.
At the very least, a factory letter or an authentication letter from a respected researcher can provide basic shipping information on where it went, when it left the factory, a basic description of the gun, and any special features like grips and finish. A factory-lettered firearm likely will have the document displayed with it at a gun show.
Why Get a Factory Letter?
Not only does it help the owner in setting a price, but it can also lend confidence to a buyer by offering authenticating documents as to what they are buying.
In 2021, Rock Island Auction Company sold a Colt Single Action Army owned by gunslinger and sportswriter Bat Masterson. Documentation accompanying the revolver included a letter from Colt Manufacturing confirming it was shipped to Masterson with a higher front sight as requested. However, the gunfighter asked for nickel plating and the letter incorrectly states it was shipped with a blued finish. Follow-up documentation confirms the incorrect finish listed on the factory letter. The gun sold for $488,750.

This May, RIAC offered a Colt Single Action Army that was reportedly recovered from the Little Bighorn battlefield. A letter from highly-respected Colt researcher John Kopec showed it was one digit away from the serial number of a Colt SAA recovered from the Little Bighorn battlefield in 1992. It also described the gun as a significant “Custer-Era” “Lot-Five” revolver while also noting the blemishes on the 150-year-old wheel gun. The revolver sold for $763,750.
Rock Island Auction sees a number of factory letters each year, especially with Colt Single Action Army revolvers. Not all of them are sent to Bat Masterson, but some collectors are interested in where guns were shipped, especially to the west, before territories like New Mexico, Arizona, and Alaska achieved statehood.
A commenter on the Colt forum wrote that anyone who owns a Single Action Army that was made before World War II should get a factory letter for it. First generation Single Action Army revolvers were made until 1941.
The first step for someone wanting to assess the true gun value is to check the “Blue Book of Gun Values,” which will provide an amount without consideration of its history.
Experts say that documentation can be helpful in assessing gun prices, but that sometimes there is no tangible evidence tying a gun to a historic person, place, or event.
Guns with a military or law enforcement pedigree may be attractive to some buyers, so a factory letter can often provide information on whether it was shipped for military or police use. Experts recommend always confirming a factory letter, saying “Paper is generally easier to forge than steel.”
The NRA Museum website reports that documentation — and especially the type of documentation — can make a difference in valuing a weapon. Masterson’s revolver is an example of that. The finish was recorded incorrectly in the factory letter, but follow-up documents confirm what Masterson requested.
Remember, the letter provides information on where and to whom it was shipped, and what features it had when it went out the door. Those things are of interest to collectors and can contribute to the value of a prized family heirloom or inherited gun.

What ISN’T in a Factory Letter?
The history of a gun and who owned it can weigh heavily on its value. Historical significance and the credibility of the information are the biggest factors in historic attribution. Here is an example: A factory letter might show that a revolver was shipped to a certain western outlaw. It doesn’t confirm the current owner’s affidavit that years ago a deputy marshal gave the outlaw’s gun to the owner’s great great grandfather.
Skepticism must rule with historical attribution, but a factory letter can help bring ownership or chain of ownership into focus. On the other hand, it can also protect the potential buyer from ending up with a forgery.
Experts recommend being very detailed in a record request for a factory letter. The more information on what is being sought in a request, the more likely researchers can find something interesting ̶ if it’s there to be found.
Commenters on various forums acknowledge that a factory letter is at least a good starting point for research into a gun’s history.
Self-education is the best thing a collector can do to avoid getting hung with something that might not be what is professed. A serious gun seller might also consider a free gun assessment with Rock Island Auction Company if they are considering gun consignment. Talk to other collectors and learn about the gun type that interests you most.

The recently-completed premier auction had more than 100 lots that included descriptions specifically stating that some type of authenticating letter or research was included. These are guns without the flash of Ulysses S. Grant’s revolvers (that came with plenty of authenticating documents, too), but just nice, collectible Colts, Winchesters, Marlins, and Smith & Wessons.
A factory letter or an authentication letter may not be necessary for the collector keeping a gun for themselves, but if you are curious about a weapon’s history or are planning on selling your gun, most commenters in the various forums recommend a factory letter. When a collectible firearm changes hands, documentation can provide value, but also offer peace of mind.
257 Roberts: The Second Chance Cartridge

Excerpt from the 2002 book NRA: An American Legend by Jeffrey L. Rodengen.
After the Olympic Games of 1924, the International Olympic Committee had eliminated all sports not of major spectator interest and those that it called “mass athletics.” Among those events dropped under this ruling was shooting. The National Rifle Association and the International Shooting Union protested this decision and conducted an ongoing campaign to have rifle and pistol shooting reinstated, but their efforts remained unsuccessful until 1931, when the NRA Board of Directors appointed an Olympic Rifle Committee chaired by Milton Reckord and an Olympic Pistol Committee headed by Karl Frederick.
That same year, the International Olympic Committee ruled that it would bar from competition anyone who had accepted a cash prize or who had competed in a contest in which a cash prize had been offered. By the 1930s, cash prizes, though small, were still being issued for shooting competitions, and there was scarcely a single experienced target shooter in America or in the world who could meet the committee’s standards. Both of NRA’s Olympic committees were forced to draw upon unknown shooters of little competitive experience to build their teams.
The International Olympic Games Committee did not consult NRA’s Olympic committees on the arrangements of the shooting match or on the construction of the shooting facilities. This slight was further complicated when the International Olympic Games Committee announced that the Sergeant of the Los Angeles Police Department would be “in charge of shooting” at the Olympic Games in Los Angeles—despite the same committee having invited NRA and the United States Revolver Association (USRA) to assume some charge of the shooting facilities.
The result was a fiasco. Although fine for police practice, the Los Angeles Police range was neither designed nor built for formal competitive shooting. When NRA’s Olympic Rifle Committee reached Los Angeles, they found that the shooting house was several yards too near the 50-meter targets and out of parallel with the line of the targets. To attain 50 meters, the shooters had to press back against the rear wall so that men moving from one point to another did not interfere with those who were shooting. When the foreign teams arrived, most of them flatly refused to shoot until the range was rebuilt.
Although the Americans had bent over backwards to abide by the rules of amateurism, they soon found that their competitors had taken the rules more lightly. General Reckord and Karl Frederick had been associated with international shooting long enough to recognize men who had been shooting in international circles for years. Frederick had competed personally for cash prizes against a number of them. If they had protested, however, the entire shooting program would have been eliminated, so they decided to make the most of a bad situation.
The shooting events were a major disappointment. But at least to the shooting world, the events were better than no participation at all and they provided the basis on which future competition could be built.
