I'm in the process of dealing with my brother-in-laws estate and ran across this Colt Diamondback 22LR revolver. I've got a Glock 19 and a Sig Sauer P226 in 9mm so I initially turned my nose up at the 22 caliber, but after a little research, it appears that it's actually worth something. My question is why would I want it, and how much should I pay the estate for it? I believe it to be a 1979 model with 6" barrel.
