I've ordered a screw the was missing and a cleaning kit for it from one of the sponsors/advertisers of the forum. Not a big order but hey, Karma...
By the way, my screen name ins in recognition of my father, who was a Navy Corpsman in Korea and served with the Marines. N. Korea was not a signatory on the Geneva Convention and had a habit of picking off the Corpsmen if they could ID them.
Dad was issued an M1carbine but tossed it after it slid down his arm a couple of times while working on a wounded Marine, hitting the injured man. He was finally issued a .45 Colt which solved the problem. Before going into combat Dad would tape ampules of Morphine to his rib cage, under his arms. This kept the morphine warm enough to inject into the wounded when needed.
