An Herculean report, for a guy who joined this month...!
I'll bet
any collector would like to have these pieces (for the right price--"right" being relative term). The idea is to collect the best examples in your area of interest. The market determines the price, and any gun is worth exactly what someone is willing to pay for it, at that time. The cutaway is probably going to be darned expensive--one of however few stamped in Farsi. I'd say that's pretty rare, presuming their authenticity. But without someone who wants to collect it, it"d be worthless. So, I'd buy it, if I could afford it. Then, when another one came along, all original and minty, what to do? Well, gotta have that one, too!
