An American glove mould,made in Trenton New Jersey and designed for making rubber gloves.
There are two here to choose from ($85 each) one with 1992 stamped at the bottom and 1996 on the other.
They are made for a large hand size.
Approximately 300mm high,good vintage condition with some latex residue around the base,easy to clean up if desired.
These have almost all gone,there are much larger ones at the shop also.
