I have wished to own a small vintage refractor for a long time and a couple of weeks back, I bought a "Unitron 133-n Junior". It is going to be placed in our living room (wife accepted it!!!)
When I got it, I immediately noticed, that it didn't say Unitron anywhere. With a lot of help from fellow astronomers on the danish forum astronet.dk , I learned, that it might be a Nihon Seiko (see the "N.S. Patented" print on the focuser on the photo below): https://www.astronet...&p=14277#p14277
I am trying to find out exactly which brand, model and year it is???
I have trawled the internet (including this forum), but I can't find any references to the model. Some close, Unitron 133-n and Unitron 760, but I guess, that since mine doesn't have Unitron printed on it, it isn't a Unitron.
Does the "N.S. Patented" mean that it is made by Nihon Seiko or merely that it is a noname made on licence?
On YouTube, I found, and watched, several very interesting videos by Dave Trott, and in this one, Dave mentions a Unitron 760, that, besides the "Unitron" print, looks exactly like my telescope:

But I can't seem to find an exact match??
If anyone have some material about this telescope, I would very happy, if You would share it. For example an old advitice or catalog?
The tripod legs are extremely pointy, so one of the first things I need to do, is make some "shoes" for them (3D print), to protect our wooden floor.
And also make some sort of spreader, that can be mounted without making holes in the tripod. It seems, that theese models didn't have any fixture, chain or spreader.
