WoW! I have not seen a mention of the nylon 66 in years. I had one of those when I was a kid. Almost 10 years ago now I saw some of them at a local gun show, the guy had about 50 of them stacked up in all different conditions and was selling them for $10.00 each.
It was a great little .22. When I was a kid, my uncle owned a sporting goods store where we lived, he would give us all the .22 ammo we wanted for free, and gave each of us kids a nylon 66. He had one storage room full of nothing but nylon 66's and crates of .22 ammo, the nylon 66 sold like hotcakes for him and almost every one in the area had one. I must have put at least 20,000 rounds a month thru that thing for years.
