Vintage pneumatic brass railroad train engine bell and salem 506 ringer. Bell is solid brass and weighs 44 pounds. There is no make or model number on the bell. The ringer is a Salem 506, Graham White, Double Acting ringer (6 pounds). The ringer is currently not working as it has no "O" rings. I tried to contact Graham White as their add for the ringer says it has "easily replaced "O" rings". They would not tell me the size or say there was a kit, so they tried to sell me a new ringer! I bet some of you railroad gurus out there know this information (if you would like to tell me, I would love to put this back in action!).
