Form A.A.S.3 issued by the U.S. Aircraft Armament Section in 1918. I thought it could be interesting.
very interesting to note that .30 links for Marlin and for Browning are two separate entries !
Jean-François, I’m glad this is of your interest.
Also, in July 1918 it was reported that Marlin guns suffered of frequent stoppages and below is an explanation of the problem and proposed solution by redesigning the links, which may indicate that a modified Marlin link was made late in the war.
Thanks for this information : very interesting.
to illustrate this question of links, here is the 10-link chipboard box for the unified links for both Marlin and Browning.
