Please let me know what the marks on the brass disk means about my rifle.
The 1,2, and 3 refer to barrel condition...but there's really 5 ratings, only 3 need to appear to the disk though:
0: New
1: Like new, very little use
2: Very good to good condition
3: Good to Average
4: This rating would cause the rifle to be rebarreled or removed from service
The Swedes, like the Swiss, were
very picky about the condition of their troops firearms, so even a '3' rating is likely to be a very good barrel by surplus standards.
The other numbers refer to bore diameter. Yours appears to be 6.50
The marking "Torped Overslag" refers to where the round will hit at 100m using the m41 ammo. The original rounds had a round nose, they changed in '41. If there was a .5, 1, etc. It would mean the round would hit .5m, 1m high at 100m. The "0" means yours should hit dead on.
I recently picked up an '02 M96 and a '41 M38. These are some of the nicest Mausers ever made, and the 6.5x55 round is a lot of fun.
