Antique Hand Molds Brass Pre-1800?

This is three antique hand molds. The first is a brass mold with conical bullet, it is unmarked and appears to be hand made. The handles are mismatched but firm. The second is a brass bodied unit with a steel cover and unmarked. The handles look to be commercial. The last is a handmade 36 caliber round ball mold in very good condition with very little oxidation. These brass molds appear very old and may be pre-1800.
