I have about 13 hours to think about it.
I've been offered a Marlin 336 for my Marlin 1894C in .44 Magnum.
The 336 I've been offered is outfitted with a good sling, a Burris 3-9x40 scope with mount, and has had a pretty good action job. It's pretty slick.
My 1894 is bone stock.
The only thing that sort of bugs me is that the 336 is missing its front iron sight for some reason beyond my comprehension. I'm wondering what kind of expense is involved in replacing it.
Edit: I've gotten to handle the 336 in question and seen it myself. It's in good shape, very minor wear. Also has the extension on the hammer to make it easier to manipulate the hammer with the scope on it.
