WTB: American Armament Corp. 37mm

I’m working on my Dardick Tround book chapter about David Dardick’s early ordnance work, when he was employed by the American Armament Corporation (AAC). The company made 37mm cartridges in four case lengths and I need an example of each, hopefully in excellent condition. 37x87R, 37x142R, 37x178R, and 37x203R. Email me at mooneypilot@att.net.
