I remember the ads. I finally found a nice Nylon 66 on Gunbroker a few years ago. Sweet.
It was on my list for years but I finally got a Nylon 66, unfortunately it was inherited when father in-law passed away. The thing is in near-perfect condition. Even has the box and the green plastic “case” that it came with. They still aren’t worth much of anything, but it was always a nostalgic thing with me because I remember grandpa always plinking out back, picking off ground squirrels and moles with one... he would sit out there in his chair, peeling an apple or whittling, waiting for something to move
