I am fascinated by firearms, and have collected an extensive library of books about them. I am considered by many people I know to be an expert on the subject.
One of the books in my collection that may be of particular use, Small Arms of The World (1968), has specific instructions on how to load, fire, field strip, and perform maintenance on a wide range of guns ranging from WWI to the middle of the Cold War.
I am always willing to answer any and all questions relating to firearms, and am available to act as a firearms consultant to any mod team that could use the help.
If any mod teams are interested you comment on this post or PM me here on ModDB.
