If it's 1100 fps from back then, it's the 52. Side-cocker, right? Believe the 48 was a barrel-cocker at 1000. If it's a barrel-cocker I must be thinking too far back. Sweet airguns, all the RWS, But $500? Wow, that was a lot for then. Shouldn't have been more than about $300. Cool piece for critters in the back 40.
