I donated the Hensley & Gibbs hammer mold from the 2007 thread. Hard to believe that was nearly 16 years ago. That hammer mould made its rounds until one of the members decided he really liked it and kept it. Much to the dismay of everyone.
Hensley & Gibbs never made hammer molds. They outsourced the production of the ones that had their name on it because it was too infrequent an item to make in house. They were never happy with the quality so they stopped offering them. I still have one. I haven't used it in 20 years because its a PITA to use. There are modern designs that are much easier to use.
