I can usually determine a fair market value for a gun if I know the model and condition, but this one has me stumped. I have been offered a 2'nd generation Colt SAA, blued with 7-1/2 bbl. That's common enough. However, this one is a commemorative produced in 1961. It originally had a gold-plated grip frame, trigger, hammer, and cylinder pin. A shooting buddy bought it two years ago UNFIRED and promptly began using it as a cowboy action gun, absolutely ruining the collector value. Worse, he didn't like the gold plating and removed it, so the gold parts are now nickel, since that's what was underneath the gold. He has shot it 600 times and now wants to sell it. Other than the missing gold plate it looks new and shoots great and comes with the hardwood box and all papers. He's asking $1,200, which seems about right. I just am not sure. Help me out here.
