Seller's Description:
INTRODUCTION:
I have a collection of nine Rohm model 63's. Each one will appear in a separate auction listing on this auction site until sold. Two in .32 caliber, one in .22 caliber and six in .38 caliber. This introduction will appear in each listing. I have collected these because of the novelty of having a cowboy style frame in a caliber higher than a .22 (except for one of these). Traditionally, cowboy (or Western) style revolvers have been single-action because that was the prevailing technology in the old west. So from a nostalgia standpoint, these single-action revolvers have endured. However, if I was going to need a revolver in self-defense, you could bet that I would want a double- action with a sweet trigger. Well, that is what the Rohm 63 is. Except for the High Standard double action revolvers in .22 caliber and the Colt Thunderer and Lightning double actions in higher calibers, I do not know of any other double action revolvers in cowboy style frame. The Colt revolvers were made around 1900 and if there are in good shape they are bringing high prices as collector pieces. But they would not be desirable as shooters. Having said that, I collected and had a top gunsmith mechanically rework all nine of these Rohm revolvers. They have been completely disassembled, cleaned, deburred, adjusted, bad parts replaced, lubed and reassembled.
Rohm was a German manufacturer whose guns were imported by a number of companies such as RG Industries of Miami and Liberty Arms of California. They were famous for their cheap .22 Saturday night specials. These model 63 revolvers were engineered pretty well and given proper ammo and care, they are quite serviceable. The most common problem reported has been problems with owners shooting high pressure ammo in them. These should have standard pressure ammo only. High pressure ammo has caused some to have their barrels jarred to the point of being slightly loose where they are joined to the frame. We saw some of this in rebuilding them. All such barrels were refitted and re-pinned with oversized pins. But the design of the revolver is really very good. The gun is alloy frame with steel cylinder, steel barrel and a very sweet double action trigger. The pictures are pretty clear so you can see the features well. If you like the nostalgia of a cowboy style revolver, but would like a double-action with a sweet trigger, this might be just what you are looking for.
