sir,

I purchased a m57 via Cabelas, 23073 matching bolt; shark fin sight, and Lyman rear peep and the fold down rear site.  The barrel was marked 30 B 217

Questions:  is the front trigger guard screw the only one that should have scrollwork on it?  my other two screws are plain, and should the barrel band be installed so the  pat date info is on the right or left?  and what does the B and the 217 refer to?  thanks. Brian

Jwa,

thanks, in answer .22LR, also, on the trigger guard at one of the bends there is brass looking metal, so the backside of the trigger guard is blued (i.e., black), the outside what is visible when screwed to the stock, is thining blue but mostly grey/browning metal, but for a 1/8 ” x 3/8″ patch of gold colored metal..thoughts?  thanks…the underside of the barrel has evidenced of cold blue, I used a cotton swab with rubbing alcohol to confirm..

A while back I provided a M57 .22 LR #20842…I took a look at the underside of the barrel as requested, it is B inspector stamp, 217, triangle and 29 dated . the barrel looked like original bluing however this is a barrel where the exposed topside has the browning patina with 30-40% bluing…I was surprised how nice the bluing; or how black it was; is it normal for the letters to be black or should the roll marks B, 217, and 29 be white/silver?

Also, this barrel has the 3/8″ line on the barrel and a 3/8″ line on the receiver section for alignment like I have seen on M72s….Additionally, the proof marks are offset like one reads about for telescopic winchester…

Do you know if it was common to not center the proofmarks on the topside of the barrel but instead place them laterally just above the wood; to align the barrel on the M57; and stamp an inverted triangle before 29?

Break, in response to my other gun, the takedown screw is the one with the short lines around the circumference of the screwhead..if not normal for the M57.do you know what model used a takedown like I am describing?  I thought perhaps it was different to indicate the takedown screw…the design looks like a winchester screwhead..I just cannot recall what model I have seen it on.

thanks.
