Hi All
Is this is the right forum section
Recently acquired a Crossman 1300 MK2 Medallist overall in good order ,however it was not holding air , having sourced a seal set off the ‘Bay’ to replace all the obvious seals now I have taken it apart & I now have a question.
I have stripped the gun apart & with regards the brass valve body- it would appear that there is a thin flat rubber washer seal which is ‘stuck’on the end & separates the valve base 760-073 from the internal sleeve 130-057
Is this seal normal - can I fabricate it out of sheet rubber or silicon was it a previous repair do I need it / will an o ring suffice ?
Your comments as always appreciated
Regards
james
