Air Gun from Trigger to Muzzle

Air Gun from Trigger to Muzzle by G.V. Cardew, G.M. Cardew, and E.R. Elsom, published by the authors, this is a 1980 reprint, originally published 1976. 96 pages, book measures 5 3/4 x 8 1/4",condition is very good, minor fading on covers. This work is solely about spring operated air weapons, many of the facts mentioned apply equally well to pneumatic and gas operated weapons. The authors try to give you a better understanding of the processes that go on inside your air rifle when you pull the trigger. Very technical with drawings and graphs. The first chapter has a few neatly highlighted lines. Otherwise very clean. I ship USPS Media Mail with delivery confirmation.
