Try contacting forum member 7.62x51 through the forum e-mail system, or by PM. Haven't seen him posting recently, but he may still answer. He has CDs with the complete 1919A4 set and the A6 parts, as well as the M2 tripod. They are not free, but were painstakingly copied from the 1948 revised set at the National Archives, as I understand. Cleanest set of drawings for the Browning I know of.Got it. Thank You. Do you happen to have the whole set for all of the parts?
