1929 SC SBT Barrel Flat Codes Help Needed
 

Please see the pictures; I think I've deciphered two codes as 1. the struck barrel weight (3lb 2oz) and 2. March 1935 Service Section Remington Repair Code (AD 3).

However, on either side of the weight and proof marks are two other codes that look like HT/A A (on the left) and the numeral 4 (far right). Are these inspection stamps?

Like much in life, I don't have clue but will wager someone does....help?

Thanks in advance.

Markings
 

The large A by itself is the grade or type steel in the barrel. Acme. I believe. M

Markings
 

The number four would be the grade, C, I believe. M

What is the “M” in your replies?





.

A D 3 is a Remington service ir repair code.





.

“Mark”

Oh, his name… duh… sorry.

Thank you, all, for your replies and help. The code that's most puzzling is the small strikes that look like HT over A to the left of the Acme steel A.

Maybe it's H7? Any guesses or ideas?

Thanks!

P.S. heading north to the woods for a few days - no internet or phone and will check updates to say thanks again by the end of the week....

The most accepted meaning of HT/A is High Tensile Alloy.
