Up for sale is a 1953 Marlin 336 SC in 35 Remington with a Williams peep sight.
$500 shipped to your FFL CONUS.
The only trade I'd be interested in is a RH Remington .223 Varmit 12 twist rifle.
She has been well cared for and the pictures will tell most of the story.
For full disclosure- The magazine cap screws are slightly bubba'd, the rear sling swivel is attached just prior to the factory mount, and the appears to be a hair line crack in the buttstock at the tang. Which seems to be inherent in these rifles.
I ran one box of shells through it and it functions flawlessly.
More picture can be sent if needed.
