BAM B50 firing valve seal (Chuntsman). I was looking for a firing valve seal for the BAM B50, the so called Chuntsman due to it being a sort of copy of the original Daystate Huntsman. I finally found one via : sniper@canadianairgunforum.ca
So this could be useful should anyone need one. The mail puts you in touch with Dan, an extremely pleasant chap.
It is possible that these valves also fit the original DS Huntsman as well; I believe the original valves are no longer available.
Cheers, Phil
PS ... I did ask, and was told it was OK to put details up.
