BTW - much older machines/cabinets have a different style mounting system. I've got several machines where the "Pin" stays with the machine, not the cabinet. I've got some that have hinges that that screw to both the machine and cabinet. Most of them have the typical pin that mounts to the cabinet, with set screws on the machine.
Though I have a few that don't have set screws as they don't tip, but the wood base lowers into the cabinet.
