I have a 20 marked KE1 so it should be a Zimmerman. The 20 is very, very faint on the top of the pin. There are also a 2 and a W stamped on the pin. I think its good but after the FO U-Boat I want to remove any doubts. I tried to get the best shot of the number 20 but it just did not come out as well as it does in hand. I can see the unique 2 just like the ones I looked up on site.
