Hello George,
Each main picture I sent has a ruler showing the size. What more do you need? For this gun it is 36cm/6.75 inches long. Height is about 9cm/ 3.5 inches without the firing “pin”? As far as “hallmarks, numbers, and stamps” I gave you everything I see/have. These guns are old. Please confirm this is what you need before I submit the other 4 gun info with your same “ask”. You can always call me EST – Doug: 404-307-8931
Thanks,
Doug

Hello,

My apologies again for the delay. This is an Allen and Thurber Pepperbox revolver from the mid 1800's. It is a muzzle-loading percussion cap gun made for the domestic civilian market in the United States. This piece has some significant corrosion around the flash-holes and in the bores. The rest of the metal surfaces exhibit a dark patina, with some pitting. The wooden grips are in good shape. Given the condition of this piece, and completed auctions of similar items, a fair market estimation is 500-550 dollars. Please reach out with any questions.

Thank you,
Bo Stuck
