K4-1.



The El Paso roll mark is absent here. It was actually done away with back around the time of the Marksman series of 1" tube scopes.
The bluing has changed from "real" gun blue to something that looks almost like Jenno-lite cold black.



Turret adjustment screws and scales. There are no "Micro-Track" markings on this scope, but the turrets are somewhat similar.
Tapered post and cross-wire reticle.



K-12-C3.



Adjustable objective. It will focus down to 50 feet according to it's scale. Fine cross-hair reticle. Shown in "modern" Leupold rimfire rings.

I actually tried tracking this around a scope sighter target at 25 yards with one of the .22's. Increments are surprisingly uniform for a scope this old, and returns to zero fairly well.

More to follow...
