I thought I would try my C5 spotter on my 114 mounting for a nice grab-n-go.
It's too dangerous and I don't recommend it. If you release the altitude lock the OTA can get away from you and damage it or knock your front teeth out before you even knew what happened.
It looks like it would work and I see all kinds of scopes on Unitron alt-az mounts but the geometry is wrong here:

After that failure I got to wondering about the forward facing counterweight on some of these Unitron alt-az mountings and then became completely side tracked when I came across Company Seven's 114 and noticed it is exactly the same as mine in every detail. No date is stated in the article and this leads me to wonder if they themselves don't know.

Anyone here know the age of Company Seven's 114?

I suppose I could email and see if they know but something tells me they don't knowing how difficult it is to date Unitron.

Its a great article. Unitron fans I'm sure are aware of it. They have other articles listed like the Unitron 142 and RV6:

A few key items I noticed.
Tubes for everything on the telescope are saw cut as I marked here:

By the way. That 114 mount I would say is a later one. I do not know when they started using plastic knobs, but the earlier mounts had metal knobs.

For the focusers Unitron transitioned from precision machined aluminum to the attractive yet durable plastic knobs 1959-61.
I can't find anything for mount knobs.

Love those leather handles. Says 50's to me. And the cork is pure genius!

The plastic focuser issue is a bit deceptive. I have a 1955 Polarex in original condition that has a plastic focuser knob. I think it's like the Neanderthals - plastic and metal focusers coexisted for a while.

I have an original catalog from 1958 that shows the knobs are metal.

Yes a C90 would be a walk in the park.
I was having pretty good luck with the C5 and a camera tripod with fluid head, but I needed slo-motion controls to reduce the hairy job of unlocking the clutches to track.
A small equatorial would be safer. I did try this:

I have one Uni. All metal 62mm on the focuser..1954ish maybe 1955. I have a 1957 Goto which is the mirror image. Even the one focus knob is on opposite side.

Keith I'm absolutely stunned you only have one Unitron!
I'm not kidding, I felt my jaw drop when I read that.
I have seen pictures of it and it's a beauty. That is the bolt-on-tube, brass looking cell scope you have?
You should post a picture here if you have one handy. Its the oldest one I've ever seen.
What am I talking about I only have one complete Unitron myself!
My entire crazy collection of telescopes contains only one and a half Unitrons.
