Complete three volume set of Firearms Identification by J. Howard Mathews. These books are used by the FBI forensics lab in Quantico to identify the many odd guns sent to them for evaluation.
This set has more info and pictures than any other reference, period. This is why the FBI uses it.
Books are in very good shape.
These books run in the neighborhood of $600-700. Will trade for guns or related items in the general ballpark of price. C&R trades welcome.
