Barrel date code is A F, so March 1937. Serial numbers is in the 273XX range. Metal looks nice other than wear on the sides of the front sight band. Stock has a LOT of scrapes and dings but not appear to have been refinished. I wonder how any of each variant of the 30-S was made and in each caliber: 30-SL, 30-SR, 30-SM, and 30-SX in .30-06, .257 Roberts, 7mm Mauser, and .25 Rem. I suppose those records were lost long ago.
I've never seen a 30-SM with the Marbles Goss sight, does anyone here have one? Adding 30SR, 30SL, 30SX, and 30SM for searches. Pictures of the rifle below.
