How to adjust reticle clarity on Wien K. Kahles h/4x60 scope ?

[locknloadnow]

yes I already thought that, for target shooting it would be no problem, for deer hunting it would be a problem. I like to hunt with my old rifles occasionally, and that means I'd have to remove the scope and use the open express sights, or flip my glasses up on my head to shoot- which one seldom has time to do that in thick brush whitetail hunting. The deer go by pretty fast even when they are walking or grazing, and any unnecessary movements usually spooks them.

I was able to get the small set screw off pretty easily, but that doesn't help the inner adjustment much, it's seized inside. The set screw merely connects the outer thumb wheel adjustment ring, to the inner lens that adjusts the image. So just removing the screw does not free it up inside.

I hear you on the brute force, I used a rag to grasp the ring and was turning it with nearly all my strength and it didn't budge, and I'm afraid of breaking off that set, because all the force of that outer ring is transferred through the set screw, to the inner adjustment lens tube

the ring basically adjusts a tube with a glass in it, that is pressed inside the main scope body tube, and should float freely in there and turn with ease. It's seized up. I have to remove the front and rear glass assemblies to clean them, and got a good look at what's inside. These scopes have amazing clarity for their time, and are better than most of the made in China scopes of today. They are very easy to disassemble and clean, and are not over-engineered. You can remove the front and back glass by hand without a spanner.

the same thing happens to these scopes, that happens to old phonographs and record players, the grease gets hard and sticky and dries up, and ends up being more like glue than grease, and seizes the parts solid, and if they are aluminum alloys they get really stuck, like welded together.

this is a claw mount setup and I really like it. It latches and unlatches almost effortlessly. If they made a scope mount this nice today they'd sell millions of them. It makes a Weaver mount system look like junk.

can anyone date the scope for me ? here's some pictures
