Thanks that helps. Mine has no markings on it either. Since it was six or seven years ago since the last reference ,must have been a very small contract. It must have been made during the time period of the 03's because of all of the surplus parts available post war. The previous owner of my A3 said it came from the DCM in the 60's but I bought the rifle (not the story) because every part on the rifle was in mint condition that didn't look refinished.
