I am looking if there is a book on Vickers guns. The only info I could find is at Cornell Pub. I bought a Vickers sidelock at an Holt's auctions and I want to have info on these guns.
Any info is welkom,Marc.

How many pins on lock?

The book, "Shotguns and Gunsmiths",by the late Geoffrey Boothroyd, pages 214-218 reviews the Vickers gun making business.A cased vickers Imperial shotgun, 12G S.L.N.E. was recently listed by, John Forsey Guns, Welling,N.W. Kent,U.K for 500 pounds stirling.

Roy, thank you for the info, I not have that book but I will look after it. I have the same gun listed at John Forsey (Listed at 590 £ and cased.
This all ready helps me,Marc.
