I just got the new Osprey book "The Broomhandle Mauser" by Jonathan Ferguson. Eighty pages, numerous color and b/w illustrations, ISBN 978-1-4728-1615-3. It's beautifully illustrated with some great color photos of a C96 cutaway as well as one field stripped and another detail stripped. That's great for someone like me who hasn't taken theirs apart yet. Well worth getting for only $20.
