Manual grinder, Spong brand, VERY old (Henleaze Ward BS9)

Got it 2nd hand in the 70s. Used it to make burgers. It's incomplete. The wing nut that fixes the handle on is missing. I think I had it dipped and stripped late 70s and stopped using it. More of a museum piece than a useable kitchen item. See photos. Collection from Kellaway/Horfield Common area. Please tell me collection plans when you reply.
