We have had several people ask us about the small softcover books printed by Osprey about various types of firearms, so today we're looking at a couple of them. Osprey has a whole series of firearms volumes, including pretty much all the important military arms of the 20th century. Think of them like a Cliff's Notes version of the serious research works published by folks like Simpson, Mowbray, and Collector Grade - they are inexpensive and a good way to get some background on a particular gun, but don't have very much depth.
