Sadly, we have no information on him. We had to exclude the Leutnante from our data base as there were too many of them. However, there is high probability that his records can be obtained from BA-MA Freiburg. Be sure and tell them you are an author and give them proof or a web site link where it can be verified. Their reproductions contractor, Selke (
http://www.selke-gmbh.de/ ), will send you a cost quote once you have established exactly what you want and they have the page count. I think you will be looking at perhaps 8 pages of material at about a half-Euro a page. Selke accepts credit cards.
