Hello all, I have a chance to pick up a marlin Texan a few towns over. it's in .35 Remington. Ser# starts with an "R" is this a 1957 rifle? would this gun have Ballard rifling? seller wants $400 for it. I have been told it's in great shape- from the pictures it looks nice. any info on this gun would be a big help. thanks to all.
