Well, since you seem to have significant experience with old Colts, I will share this concept with you.

You could have a one of a kind prototype pistol modified at Colt or elsewhere. However, something can be so rare as to be effectively unknown. Thus, often there is almost no market for such items in some collectible arenas, that include guns and knives. {Coins and rare paintings are another matter. Collector experts, will declare a almost certain forgery genuine, and then a speculator/dealer/collector will pay a Million or more US Dollars for it! Insane, or is it, when it gets resold at a huge profit a few years later? Kind of like the recent US real estate boom.}

For example relative to knives, when I was a boy my father was given a large quantity of assorted old ammo that dated from the turn of the Century to about 1934. Going through some of the loose and mixed material I stumbled across two unusual 7X57 Mauser cartridges. One was in near pristine condition, one was somewhat damaged.

The cartridges initially caught my attention because they were nickle plated brass with a cupro-nickle, round nose, FMJ bullet. Further investigation revealed that they bore a commercial Remington headstamp, and the primers had a neat about 3/64" offset hole in them. Further investigation revealed that they were special factory made non-bullets that held about a 1.75" mass produced (by stamping and grinding) penknife blade blade. In other word they were Remington made (or contracted) bullet knives that functioned like a reversible pocket pencil that was common in the 1950's.

Thirty years ago, I contacted anybody and everybody, that I could find, who knew anything about old Remington knives. No one had any knowledge whatsoever of them and no serious monetary interest in them.

{Best assessment is that these knives were made as advertising/goodwill handouts for the Bannana Republics armies that used 7X57 mm, and that Remington wanted to sell to in the early 1920's. Generals likely received gifts of Remington 51 pistols and the bullet-knives. Non-coms likely got just the bullet-knives. Very few of these "handout" items would have had any US distribution.}

In any case, I hope that you got your revolver for a good price. You migt want to try partially or completely dissembling it and pay close attention to how the brass addition was manufactured and or marked.

Hope some of this is useful.
