I got a NIB Weaver T-10 scope at an auction over the weekend. I do not think it is one of the older "micro-trac" Weaver T10's tho. Looks like it comes with target knobs and a sunshade.
They were a highly rated scope in their day BUT these days you would only buy one for a retro shoot or to mount on a classic varmint/target rifle of the 1960s or 1970s. They are quite finicky to set up, you definitely have to read the instructions and record your settings in a notebook. More of a bench-rest and known-range positional sight than a practical varmint sight. A piece of history but not an everyday piece of kit.
