The is one of three police sport shirts I acquired today as part of a larger collection pictured in collector showcase:

The condition for 60+ years is phenominal as they were apparentely unissued and aren't even yellowed. They pass the black light test perfectly and are marked "Koch-Teuro 1942" along the lower seam. I shot these under less than optimonal light conditions and the eagle is a vivid green with a black swastika:

Jim, That is one heck of nice stash of goodies you acquired! So, are all of the police shirts marked the same?

Dave:
They are all marked the same so I expect they were liberated from a police depot and were unissued stock. I think I'll wear one if I ever decide to do a marathon.
