TMC or MTC I don't know how the acronym reads on these.
These were an estate find. I don't know much about them or to even be able to completely describe their condition. Overall good condition with some wear. Insides are a little waxy/oily from use.
They each weigh approximately 3lbs 1oz each and appear to be solid brass. They measure approximately 4" wide (3.5" inside), 2 1/2" tall (2" inside). They have removable tops and bottoms to each and holes in order to be put in a press/vice?
This lot includes three (3) molds included as pictured.
