Raimey, It sits on my shelf and comes out once a year for things like this;page after page of marks and their origins,about 1,000 marks in all. It showed me the difference between a squashed buzzard and a flattened eagle. Trade names seem to be long on American and short on Brits. Lots of rifle and pistol stuff I'm not into,big section on ATF definition of Curios and Relics,and some dating of revolvers.
Get it used and you'll be real happy,but $17 for the paperback is not to bad compared to what we pay for other books.
