Make, frame size, barrel length, type of sights, cylinder capacity, and serial numbers would all be helpful. Given that it says ".38 S&W Special" on the barrel, I'd guess it's a S&W since most other makers would either put their proprietary name for the same cartridge (Colt used to like to do this) or just simply ".38 Special" as it's apparently bad ju-ju to have another manufacterer's name on your guns.
