APPENDIX B
TABULATED CHARACTERISTICS OF MACHINE GUNS AND AIRCRAFT CANNON

This table has been compiled as a handy reference to the world's effort in the field of automatic machine guns and, cannon. Due to the vast number of models that have been developed from a basic mechanism, no attempt was made to list them all here. To avoid repetition, a representative weapon was chosen that best illustrated the inventor's (or manufacturer's) family of machine guns. (In the foregoing text all models are covered.) Where a weapon is known by more than one name or designation, it has been cross-indexed under each.

In the table, the following code is employed under "Use":
