I think that a 'sticky' that gave contacts or sources for spares / repairs for some of the more specialist old airguns would be a valuable resource. I am aware that some posters ask on here about 'who can repair my rifle' etc and they get an answer but a list of available expertise could/would be very useful. Or would it look or be regarded as too much like advertising?
Personally I would be happy to see names and contact details of people who could provide odd bits e.g. pneumatic seals, piston heads and other parts etc for cases where the parts are no longer available from the manufacturers.
Cheers, Phil
