Flak 36 (37mm) anti-aircraft gun

german AA gun (Detroit 2010) 4113

I photographed this German anti-aircraft gun during the 2010 Thunder Over Michigan show in Detroit. I had determined the gun was a 3.7 cm type, but I called on the Hyperscale nation to help narrow it down. Two answers came back as either the Flak 36 or earlier Flak 18. Because most of the earlier weapons were updated, I will stand by the Flak 36 label until informed otherwise.
