Hi Guys, I just discovered this forum a few weeks ago. I recently purchased a few Nazi items from an old estate sale & the EK1 happens to have the rounded 3 in the date. The pin on the back is marked L/17. There was also a Treffen Badge, EK2 w/ribbon, bronze Tank Assault Badge, RLB pins & lots of WWII papers relating to a 21 year old soldier killed at Stalingrad. Other medals and pins I'm doing some research on when I get some spare time. I will attempt to get some photos posted of the EK1 but it might take a few days as I'm not exactly a computer whiz. I'd like your opinion on this as I am no expert in this field. Thanks, Terry.
