Hi.
I have a BSA METEOR air rifle and I am wanting to service it but there are no markings on it to identify its mark type
the only stamping visible is “BSA Meteor and the Trade mark. I have looked at Mk 1,2 ,3 ,4 ,5 & 7 drawings but can’t see any with the same piston as mine with 2 ‘O‘ ring grooves
can any one help?
see attached photos.
