Your comment about the Nylon 66 just got me thinking about the 2 rifles I have from my dad’s collection. A GR8 and a Nylon 66 Mohawk. I think a 1 inch tube would be out of place on those rifles.
I had a Marlin model 60 with a 2x7 "TV" view with a duplex reticle. I can not remember who manufactured it, just that it was marketed with "TV". I would like to find a couple of those.
