It's a Holmar 60mm F15. Mount seems to have the same insides as the Tasco 7TE in the background or a Mayflower/Scope.

So this thing is in great condition, with some black crinkle paint flaking off the metal on the legs. Someone must sell crinkle paint. The mount is solid, the box is like wow.....

Alas...the lens seems to have a bit of spherical aberation, so the image is good to about 100x, a bit soft but no color. Not as sharp as the Tasco in the background.

Hmmm...it looks like the lens is air-spaced. Try loosening the retaining ring and indexing the lenses...you might be able to counter the defect somewhat. I like the spots-on-black crinkle finish.

Hi Keith,
What do you mean by indexing the lenses? I tried a thinner spacer and it was worse so I put the original spacers back.....I was thinking maybe thicker spacers ?

Jae I think he means try turning it clockwise or counterclock wise which ever you prefer, very slowly, turn a little retighten and test, if needed loosen turn slight agin, retighten and test, etc.

Now for the pretty factor , wow thats a swet looking scope, has some novel ideas in it like the small window in the mount for the numbers to be read through.Way cool.

If I might, where did you find this scope???

If the lens is showing a lot of spherical aberration, there's a good chance that someone has removed it sometime in the past to clean it, but put it back in it's cell in a reversed position.
I've seen that sort of thing a few times.
If you don't mind removing the lens from it's cell to check this,
the front lens should be double-conxex in shape, with a thinner edge thickness than the rear lens. If you find the front lens is thicker at the edge then the rear lens, they've been reversed. (Assuming a normal Fraunhofer-type achromat)

Hope this helps.

Clive.

go to any Harley cycl dealer for the best spray can of black wrinkle money can buy. Do google search on how to shoot the stuff, its not like shooting normal paint. The subject needs to be about 130 degrees F to get the paint to wrinkle properly.

thats a bad looking scope.

Hi Clive,
The lens is facing the correct way, I suppose the convex element could have been reversed but not sure how that would affect it. Thanks.

That classic scope looks nice. It seems to be an obscure model as well. Nice...

I guess the cloudiness in the objective isnt really there? light reflections?

I love stuff like that. That black wrinkle finish is the schiznit.

Thanks everyone for nice remarks. :)

The crinkle is tighter than the circle T crinkle.....it is cool. I surprised at the slight variations on this particular mount used by Tasco, Mayflower, Bushnell, etc. Seem to have the same exact axis adjustments i.e end of polar axis and little hole for the dec axis.

The lens is not cloudy but just the reflection......I'll tinker over the weekend.



This scope is an obscure one. It seems that Holmar may have made/labeled some binoculars as well but the company must have been short lived.
