Hi
This photo of a pre-war Ju 52/3m is on eBay
http://www.ebay.com/itm/German-WWII-...torefresh=true. The emblem matches those found on another Ju 52 eBay picture some time ago. The earlier photo, with dustbin gun position suggests that it was one of the auxiliary bomber aircraft. The emblem is a diving bird with outstretched wings. Could this be a KG 355 (predecessor of KG 53) emblem? This unit did operate the Ju 52 as a bomber.
