I bought a beautiful old 20 ga. Ithaca Model 37 (circa 1977) at a gun show this past weekend. It has the old Weaver Choke tubes that screw on the end of the barrel. One is marked "AP" and the other one is marked "LR" instead of the standard "Full, Modified, Improved Cylinder," etc. Can anyone tell me what "AP" and "LR" stand for and what they equivicate to in terms of choke settings?
Weaver Choke Tubes?
