I'm in the process of restoring a Bowman M140 that my grandfather had as a boy and passed on to me. I would appreciate it if anyone could give me an indication of what it will be worth when its finished (not sure whether I'll actually sell it).
It's all original parts and all brass work have polished up really well. Unfortunately the painted parts have had to be repainted incuding the base plate so the Bowman sign has gone.
Also, does anyone know where I can find a genuine pressure relief valve for it?
