Picked this up from the same guy I bought that nib 30 year old NEF 92. Used but not much. From what I found out it's a Marlin 80. No serial# but micro groove barrel. This puts it between early 50's and 1967. Has peep sight holes on the left rear of receiver but no peep. The rifle case is a vintage Brauer Bros. He was not going to include it and I was going to take it home in a garbage bag and he said keep the case. Paid 100 bucks. Wadda think? The case pic didn't come out.
