first off, that thing is in fantastic shape, it is also a dl model with full white line spacers. Man, I can't get over that wood!!!!
Also, did you notice what was on the back left side of that receiver???
that's right, drilled and tapped for a peeper!!!! Oh the luxury, the beauty of a mod 80 with a factory peep site, truly you must get one, and then get a hold of a dude here, or someone here knows the shop name, of a guy named JRH...
he makes the most fantastic replacement discs for these, they will make you cry just to look at them.
