Hello I have a BENJAMIN FRANKLIN 342 and a SHERIDAN .20 both with pump seals gone.I have tried every were to get the rubbers but without an success.
So I had some made.I wondered why they didnt make them like this but I suppose its the cost allright for a few but thousands make a difference.I am going to alter the piston and probably have them done in plastic PTFE OR DELRIN.Now if the O rings wear its a few pence and ten minutes to change.

Opinion please The Ben Franklin is back to its brass base I intend to coat it with something. Or should I leave it.
