Re: colt single action army
Well, first, who ever told you they only came with 7.5" barrels must be smokin' crack. It could be 5.5" or 4.75", as well as any number of custom lengths from the Factory. On the 4.75" the information stamped on the top of the barrel will be stamped on 2 lines instead of one long line.
The problem with SAA's is two-fold. First, many have been modified after leaving the Factory. That seriously detracts from the value. Second, there are some pretty good fakes out there that are generally only worth around $200-$300 if they're nicely done. It takes a certain amount of expertise to not get "taken" when buying First Generation SAA's. How much do they want for it?
