This one is for sale, for 150$. Have not succeeded in finding any info about this.

 

Have anyone seen this before and is it good? Or worth to add to collection of vintage scopes?

 

Clear skies!

I can't tell from the pix...  IF it has a helical rather than a rack & pinion focuser, that puts it in the late 1960s / early 1970s -- Old TOWA category.  Looks like it has the standard EQ-2.  Only 1 eyepiece looks original to the kit, but hard to tell for sure.

 

I'd offer $100.  I wouldn't go over $150, even if the mirrors are pristine, and the finder has its original (& straight!) crosshairs.

 

These Newts aren't rare in the USA, but the older ones with a metal helical focuser are uncommon.  They're more capable instruments than we give them credit for -- check out my planetary imagery made with a Classic 1980s Vixen version, versus a 2016 China-made version (also wearing a Celestron label).  Very good performance -- if you get one cheap.

Some jiggery with the pikky indicates to me that is it almost certainly a helical focuser, as Bob speculates...

The oldest one of these I've seen was branded Juiho.  Like some C8s, these small Newts are under-valued IMHO.  My biggest gripe with the Towa version is that they put theirs on an EQ-2, the same mount as the Model 305 / 60mm refractor, rather than the beefier Model 339 / 80mm frac mount (aka, EQ-3).  Some owners say it's robust enough; but, Royal, Yamamoto, Mizar, etc. put their 100mm Newts on a heftier version of the 60mm EQ.  

 

I hope the scope is in excellent condition, that a deal gets struck, and we get some test & session reports on it.
