A German museum asked me to help identifying the people in the attached photo. It was taken on the occasion of presenting a sword to the German ambassador Herbert von Dirksen (photo # 2, far left) on behalf of Hitler.   It seems to be a different one from the Kasama Ikkansai Shigetsugu that is well known, but I know next to nothing about gendai smiths, and hope one of you guys can help out. Unfortunately I wasn’t provided with a rubbing or photo of the nakago.
