Inherited spotting scope identification (1 Viewer)

Hello folks, I heard this was the place to go for experts in optics and was hoping someone might have some information on this spotting scope that I inherited when my father passed away.

I have never seen him use this and it was packed away in his army stuff from the late 60s. In the army, his job had to do with tank and vehicle weapon optics, so it makes sense if this was from that era but I don't know that for sure.

It looks like one side of a large pair of binoculars, has a tripod, and also has a disk with four smaller lenses on it that rotates but I don't think that disk goes to the spotting scope, though it was in the leather case with it. I THINK the disk might go to a microscope instead.

The only markings on it say UNITED, made in Japan, and various versions of that. It says 60x60 on the eye piece. Seems in good condition but dusty.

I can't find anything on the internet about this piece, there are other similar looking spotting scopes from different manufacturers and all wildly different values (not necessarily looking for a value here, mostly just information, though if there is value in it my father certainly would have wanted it to go to my son's education, but if not, I'm going to give it to him from his grampa) but I haven't seen this particular one.

Here is a link to it, and I apologize for the quality.

Any info would be greatly appreciated. Thank you.

Thank you for the info and the link to the other forum. I have also posed the question there as well. Every bit of info helps me, I wish I'd been able to ask my father about it.
