This is a very nice original .31 caliber Civil War era iron bullet mold. This is the one for the famous Colt Firearms Company .31 caliber revolver of the model 1849 that is known to collectors as the "Pocket Model" Colt. When it was new it would have had the "'
COLT'S PATENT" makers mark on the top of the sprue cutter but you can no longer read it because of the pitting as you can see. The sprue cutter is present. The iron displays well as you can see. The mold is frozen in place after all of the years in the ground. But it is slightly open so you can see the cavities inside. It makes one round ball and one conical bullet, both in .31 caliber. This is a nice original Colt Firearms Company bullet mold, especially for the price.
