Thanks for the info George. Darn, I passed up a nice DWM artillery AND a Navy because I thought the striations were evidence of refinish. BUT - since I own a pristine 1916 DWM with them also I am a happy camper
Especially since I own another nice 1917 Erfurt that has miliing marks in that area -so my extensive WWI collection of two checks out. Still looking for the Arty and Navy for the old collection...
