Now we're getting somewhere! This almost certainly is from Plauen, a city of 111,400 in the western part of Saxony. Yours is the only example I know of from this city. I will be especially interested in seeing a good photo of it and would like your permission to use the photo in a future research article on Saxon police unit marks. I will credit you on the photo unless you prefer that I not. You may send me your full name (as you would like it listed) via email to
donmaus1@aol.com. Congratulations on having purchased a very unique Luger.
