Need an informed opinion

I just got my 1918 DWM out of the safe for inspection and cleaning. Now let me hasten to add this is a import that I got back in 1998. I was very pleased with it because it was 95% matching (of course I now know that's like being a little bit pregnant) and in Good condition.


But I just noticed that it has a S/42 barrel with the 8,82 under the "correct" serial number (die set seems to match the others) plus the "droop eagle 63" and a "spread eagle" acceptance stamps. AND the 9MM barrel is 3.194" long!


Now the conclusion is it was rebarreled but the alignment marks betwen the barrel and reciever show no signs of being remarked. Plus the serial number matches the frame, in content as well as style. Did Mauser build this from parts left over from 1918, in the late 30's????


Could some of you more knowledgeable Lugerists care to comment on this strange collection of parts?


Thanks,
