Hello everyone. I’m new to this forum. Here recently I have had the itch to get back into gun collecting and target shooting. I stumbled across a sporterized model 98. Broke my heart as this gun is all number matching(what’s left to match) barrel, receiver, bolt, sight, trigger guard and plate all match in a low serial number. 2002 to be exact. I ordered a correct era stock to put it back to normal look, along with a sight hood, cleaning rod, and 1943 repop sling(nothing special just wanted it to kinda match.) anyways I have a few questions. I’ve found a few markings I can’t seem to find anywhere listed. The top says DOT and 1943. I found that the dot is where it was made and 1943 is obviously the year it was made. But to the right on the barrel it has a shield with what appears to be dot in it and next to that is DU. Not sure what the DU is. There are several eagles with 63 stamped which if I understand is inspector code 63. There are a few eagles with nazi marks. The trigger guard is stamped, not a solid piece. The plate on the bottom is also stamped. Any info would be greatly appreciated. I’ll try and get pics to follow
