I'm glad you enjoyed this thread Gamocfx, it's amazing how much info you can get reading through old forum posts. A schematic diagram is always good to have and easily found online.
Books are still nice to own I like Smith's standard encyclopedia by W.H.B Smith and there's Know your Sheridans by Ronald E. Elbe and Sheridan American Classic Air Rifles by U.J Backus




You find all sorts of bad historic repairs inside these guns. Someone once said opening up a Benjamin/Sheridan valve is like visiting the local escort, you never know who's been inside.

The airgunbbs has some airgun gurus which is reassuring because if you ever mess anything up you can always send it to them.

Without doubt the Sheridan is one of the nicest looking rifles (to me) out there.
I will re read this thread again and try to absorb more of the detail. Are there any books/sites dedicated to pump guns that start on a more basic level?
Thanks for sharing Chaps this has been very enjoyable.
