If memory serves me correctly that model was from the 1930s. Weavers Toll Free is 1.800.635.7656, but I bet whomever answers is not as old as your scope. I can't recall anything about them other than Weaver made pretty good stuff
If you're lucky enough to be on private land and can leave your stand up during the off season you can tie an old piece of cloth or something of the sort to your stand. I like to use an old camo bandana that I have. That way the deer get used to the movement and eventually don't bother even looking up when there is slight movement. This may just give you the time to draw your bow or raise your gun without being detected.
