Hi eveyone I am Paul from Winnipeg.
I have a working Ross M10 Mark 3 with Kahles Wien ZF 69 scope and Redfield mounts.
It has 2 markings that are the same one under the patented and one on the barrel.
It is crossed flags with a crest on top and the letters dpc from left to right in the flag pole spaces.
Any help finding out what this signifies would be greatly appreciated.
Thanks
