This hard cover coffee book by HM Shirley and Anthony Vanderlinden as an absolute must for anybody interested in A 5’s Referred to as “the bible” on this site in many posts it comprehensively covers anything and everything A5 and is the “go to “ reference and resource book on the subject.
Prices have gone up. And used copies on Amazon are going for more than new editions signed by the author. My advice is to bite the bullet. When it goes out of print, $130 is going to seem like a bargain — if you can find one at all. Look at what’s happened to Schwing’s book on the Superposed. https://www.fnbrowning.com/browning-auto-5-shotguns
I think I was looking on Amazon too. I remember like 250. That 130 isn’t so bad. Guess I need to order one and get it over with. Thanks for the link.
