This is a test of using Google online storage for my photos, but thought I’d try something that may interest some of you.
I only know of three fluted 9x19mm dummies made in Germany before the end of WWII. These are pictured below.
The round headstamped “DWM K” is illustrated in the DWM Case book as 480C3. I know of 6 of these dummies. The Spandau headstamped fluted dummy was one of three dug up together in Germany within the last 10 years. The 487C dummy is the only one I know of and was in a very good 9x19mm collection from at least the mid-1960s when I first learned of it until a few years ago.
