Here's my 1900, all original except for the grip panels:
Got it in a trade for about $200 as it didn't work properly, but come to find out it was just a $6 spring missing so I guess I did pretty good.
I was actually thinking about refinishing it, but after a complete disassembly and a good clean-up I found that it was way to nice to screw around with so I just lubed and assembled it again.
This is a nice little shooter, the barrel sits very low in the frame so the recoil doesn't feel as snappy as in other straight blowback .32s. It's a bit cumbersome to disassemble due to the design, but the craftsmanship is outstanding. You just gotta love the fit and finish on these, makes you wonder how much it would cost to produce it today...
