Hi I recently bought a couple of tired air rifles which I would like to restore, however I am struggling to identify what models they are. The first is a BSA Meteor but I don't know what Mk it is the serial no. Is T18119 which I believe would make it a Mk1 but the stock appears different to pictures of Mk1 rifles i have seen. The second has no manufacturers name or serial numbers at all, it has a barrel locking catch that needs to be released before the barrel can be broken to cock and load the gun can anyone help with identification of either rifle?
