Not sure if this guy is a Falconer or not. It could be a member of the public. This particular photo is identical in style to other that I have of Hans Knoespel and Hans Crusius so I think it is fair to say they were taken at The Falconers Meeting of the Gau North West and Gau South West at Gartingen 25-27th Sept 1937.
If anyone has any information .
