I have a set of 1” Talley LW’s that I believe are extra lows. Just took em off a rifle matching your description. They’ll work with a 36mm objective scope but a 42mm is a maybe.
I did grind on the rear mount a little bit to try to make a Leupold 6x42 work, so I doubt they’re worth anything.
That said, if you’re interested, pm me your address and I’ll send ‘em to you. If not, no worries.
