I recently acquired a Lyman STS in 20 X in near mint condition. The problem is that the rear elevation adjuster refuses to turn, ie will not move up or down. This is a three point, "micro click" mount. Initially, neither adjuster would turn. I loosened a screw in the top right corner of the mount, which goes through that slotted part there, which I believes serves to lock the adjusters in place after you have them set where you want. It appears to tighten on a small piece of metal, about 1/2" long and very narrow that juts out from a slot in the adjuster body (both adjusters). Loosening this screw freed up the windage adjuster right away, it works perfectly. The elevation adjuster still won't turn. I cannot see any rust/corrosion etc anywhere. Like I said the scope appears mint. There are three very small screws around the outer perimiter of each adjuster which require a jeweler's screwdriver to move but I cannot budge any of them, but I don't think they have anything to do with moveing the adjuster up or down other than to hold the outer part of the adjuster to it's inner rod. Like the small screws in the top outside of a Leupold tall turret which allows you to loosen/remove a thin turret and put on the wider one. Anyone out there familiar with this mount that can offer some suggestions ?? Thanks in advance.
