I can't help you with the value of your handgun, but you sound a bit optimistic to me, since it needs refinishing.

Bass Pro Shop usually stocks .32 long, as does David's Gun Room, Bull's Eye, and American Classic Marksman.

I like .32 caliber handguns. The flat wadcutter bullet is actually a better choice than a round nose for transferring what little energy the cartridge has to it's target.
