Warranty might still be valid. 1993 +25= 2018. Let's hope you do not need to send it in for warranty service.

1993 ?, according to Company 7`s website is states they were introduced in 1980.
See down near the bottom of the page, here..

I thought that they stopped selling telescope in 1993. The 131C was in the 1985 catalog. However, research shows that Unitron might have stopped selling scopes in 1992 not 1993 like I thought. I do not know when they stopped selling the 131C. So even if the last 131C was sold in 1990 the 25 year warranty is good until 2015. Does anyone else have a later catalog?

According to the Company7 article it does look as if 1992 was the last year they sold scopes. It states the 131-C and 132-C was introduced in 1980, if they only produced 100 of the model 131-C`s and ive heard less than that of the model 132-C`s, i cant imagine that they were produced for very many years, they must have only produced a very limited number per year, maybe 10 or 20 if as you mentioned it was still shown in a 1985 catalog
It is interesting stuff

Now its a little more confusing as to when the Unitron 131-C`s were introduced/produced.
Company7 states 1980, but on this site with all the vintage scope manuals and catalogs it shows a 1977 4 page black and white catalog courtesy of Neil Barnett.
And the 1978 Unitron catalog in German shows the 131-C in it.
http://geogdata.csun.edu/~voltaire/classics/
Does anyone know the actual history on the production of these 131-C`s ?

According to Unitron they sold the 131C untill the early 90's. However, do not even think I repeat, do not even think of sending it in for warranty service

I got the info from someone that worked at Unitron. They were also in their 1992 catalog, but those are very hard to find.

Thanks Johann, they must have only produced/sold a very limited number of 131-C`s per year then.

None of mine have a serial number. I think they only put serial numbers on the ones with the green coated lenses.

Finally had some time to clean up the mount, i first cleaned it with Goo Gone, then done a final cleaning with Aurora 3000 hand glaze, the Aurora contains no wax or silicone, it removes 3000 grit or micro scratches and leaves a glass like shine.
The image doesnt do it justice but it looks like brand new now, i couldnt be happier with it.
Next i`ll work on cleaning up the tripod, it has the usual
normal scrapes and dings from use, i`ll run one of the legs up to the guys at PPG Industries and have them match up the stain, they`ll work on it until they get it perfect.
