A really nice unbeaten-up K31. The buttplate is still shiny, magazine serial matches, wood is mostly unblemished except for one decent ding which will need the hot iron and wet tshirt treatment (no Andrew Tate, not that treatment.)
Came with a sling and muzzle cap, is very smooth and late serial numbered 1954 opens much easier than I remember my old one.
Timento load some 150 grainers. Amazing how similar 7.5x55 is to .308
Like, almost identical except the swiss is a bigger shell. $1590 from Cleavers. I sold my old one for $1500 with a shitty scope, good dies and a bag of brass back in 2017.
Looks like someone must have just deprived you of the pleasure of removing the cosmoline otherwise a virgin. Hope they stroked her gently for you. But your big enough for her to think she still is.
