My 1959 Kenko has that same engraved badge with DAYLITE also engraved above the white lettering, where your JTII sticker is - can you see anything there not filled in with white?

 

The circular inspection sticker definitely dates it as mid-late 70s. It's not the chartreuse and purple variety so I'd say 1978 or so.

Nothing in there.

Hello all! The info here is amazing. It’s wonderful having a source for it. I have a brief question. Tanzutzo. The diamond “z”. I most likely spelled that wrong. Are these optics of similar quality to other Japanese optics? I have an old 50mm Jason. I’m missing parts and considering buying a celestron to rob the eyepieces, finder, and tripod. I guess I’m asking if it will be better than the celestron.

I haven't been in this thread for years!  It;s amazing how the CN classic crew from 9 years ago (myself included) thought they had the symbols all settled.  We have learned so much since then.  I wonder what we will learn in the next 9 years  :)

 

On diamond Z, my experience is that diamond z indicates a significant drop in quality from the predecessors Circle V and Circle T.  Diamond z is still superior to Walmart junk of today, but not by as much.  YMMV

I'm not an expert by any streach but feel Steve's nailed it. If you need some diamond z parts I have an old tasco 60mm you can have for shipping. PM me.

So if you had attachment to one, it wouldn’t be a total waste. That’s all I needed to know. Given the scopes original cost, I knew it wasn’t one of Jason’s best. But I put the one 6mm ep I had in there and was surprised at how sharp it was. And that’s with a worthless ep. cool! Project time. Thank you guys!

Look at the Vixen symbol on the early LV 30mm eyepiece in this thread  https://stargazerslo...-vixen-lv-30mm/

 

I have not seen the big V before on any other product. Later LV 30s had the standard circle-V.

Having bought an original release Vixen LV eyepiece, these all have the big stylised "V" winged with 2 speed-type symbols each side logo, same as the 30mm I posted about above.

 

Later Vixens, including the LVW range, which were made in Japan, returned to the single circle V, which some products, such as their Moon filter still have.

 

However my NLVW 30mm and NLV 50mm do not carry the circle V or Japan on them anywhere.  

 

Do the Vixen NPL, SLV, SSW or HR ranges?

 

Switching to refractors, are there different markings and labellings between the scopes made in Japan compared to China. 2 respective examples would be the A80M and A80MF achromats. The former is more expensive.

 

Ditto for Opticron binoculars where production moved from Japan to China.

Back at post #270 Juha posted a focuser that started another discussion about who was circle K?

I recently bought an older Kenko and it's engraved just like the no name one he posted, but it's a 710mm alt-az instead of a 910mm GEM.

Kenko-Focuser.jpg

These same stye circle K scopes with white boxes and white tripod legs were sold as Daylite and King (KOL).

Kenko TA 710.jpg

Here's a TA 710 like mine from the Kenko 1967 catalog....

 

King KOL T 219.jpg

....and here's the same scope from King KOL 1970.

I've seen some alt-az ATCOs that are very similar,

but In my files I have a photo of a ATCO that's just like these.

 

So far I've seen circle k's on Revue, Dan Beam, O.K.K.K., Yamatar, Prinz, and even some Tascos.

Any others come to mind?

Wow this thread really goes back a long way. But since it fits my question so well I will post it here rather than starting a new one. I've tried to read though this entire thread but have not seen this one before.

 

Is anyone familiar with this symbol?

 

P1030088(r).jpg

 

I don't know whether or not it'a a makers mark and if so I don't know whose. It appears on the focuser cover of a late 1950's Sans & Streiffe 50mm Cosmic Finder. I have come to realize that this scope is an exact duplicate to the Bushnell's 50mm Sky Rover, right down to the Silver Gray Hammer-tone tube color and use of a very bright contrasting color for the rest of the trim.

just a guess:  it looks like it could be meant to incorporate the letters S,P, and I.

I've blown up the image a bit 

 

P1030088(rc).jpg

 

The more I look at it, I wonder if it could be an Astro-stylized version of the Rod of Asclepius.

 

Esclapius_stick.svg.png

 

Greek mythology says Asclepius was the son of Apollo. A healer killed by Zeus and placed in the heavens as Ophiuchus. Still doesn't tell me if it is a makers mark or whose. I wonder if other San & Streiffe refactors have this symbol?

Anyone figure out what OTC inside a diamond is for? I see it mentioned briefly here, but with no real conclusions. This is on vintage Bushnell equipment. Thanks!

IIRC it represents the "Oriental Trading Company"

If you haven't visited the minature binocular web site do so. You will find a plethora of information on symbols for binoculars that carries over to telescopes as well.

 

UPDATE:  See page 16 of 68.  Scroll down to find much detailed information on OTC. "Oriental Trading Co and Toyo Jitsugyo K.K. were considered affiliated divisions of the same entity."

 

The site now has dozens of sales literature scanned for binoculars of which many include telescopes.

Circle W

 

I apologize if this has already been mentioned, but I found several threads where members were asking questions about a Circle W on some Jason scopes. I came across this one on ebay that included a photo of the inspection sticker.

From the post below, it appears to be a late 70's inspection sticker with a "12".

https://www.cloudyni...arch/?p=7256328

 

According to the list below, that number corresponds to "JB 12     Orora Kogaku Co. Ltd. - Aurora Kogaku Co. Ltd."

http://home.europa.c...ope/jbcode.txt 

 

Finally, this link has a little more info stating "Kyoei Shoji Co., Ltd. of 1-17-6 Ebisu-Minami, Shibuya-ku, Tokyo 105 Japan as the exporter/supplier of Aurora brand photographic equipment."

Some of these stamped symbols on sub-assemblies are the mark of the hardware maker, not necessarily having anything to do with the assembler of the telescope.  Tough call.

Thank you Stargoat! That is the first real lead I've gotten concerning this mystery. I sent an email to the miniature binocular people with what information I have.

I have an SPI 60mm f/20 that is a clone of the Astro R-61, it carries the diamond-OTC mark, yet I believe we are just about certain that these were made by Astro.  So the mark may be that of the exporter and have not as much to do with the factory that made the scope, as we usually think.
