My last post was incredibly vague. The serial number is listed as being in the Griffin and Howe archives. The last few years I've been using a well worn 1937 Model 70 30-06 for my deer hunting. It has proven to be hell on deer with 3 shots accounting for 3 bucks. The 2 1/2 power Lyman Alaskan with the Lyman dot reticle is still a pretty darn good scope.
