Ku Luger on Gunbroker

The Luftwaffe and KM are very well documented...I have several references on each that list all of the waffenfarbes and branches. I have never been able to find any refernece that connects either Luftwaffe or KM with any kind of branch that was labled Kusten anything....other some navy units were detailed with coastal patrol duties. The Police designation that the Auto Mag article apparently alludes to is even more enigmatic. As I said, I have not read the article and know that I should (I may have to eat a lot of crow afterwards) but I have talked at some length with a fellow who put forth this coastal police theory. This was several years ago and for all I know may have been the author of this article. I will say that the better one understands and knows German military organization, supply and operational history the better chance one has to understand the Luger (and all other German arms and equipment). Unfortuniatly it seems as though the reverse is more common in actual use...that is those who try to bring to light German military organization and history thru looking at Lugers!
