Some more info.
Thanks so much, I'm checking on the Mauser.
I read that the large ring Mauser trigger guard screw holes, From center hole to center of other hole should measure about 7 7/8 or 7.830. This one is approx. 6.50.
33 1/4" LONG
Measures by back swivel: 2" WIDE
BY NOSE: 2 1/2"
BARREL CHANNEL: 1 1/4"
FROM REAR SCREW HOLE TO END OF BARREL END / NOSE: 20 1/4"
I would really appreciate any help, I have researched this till my head is about to burst!
