I think you hit the nail on the head Steve. We knew of rebranding such as Pentax and Jupiter but just like you mentioned i think it goes deeper. For example we are seeing brands for Eikow and Hino ( optical manufacturers/wholesalers, both?)thinking they made the scope but as you found out the trademark HOC was Hitomi optical machine company who was also a manufacturer. So did Hino and Eikow assemble the scopes, Hitomi HOC made the scope or at least parts of the scope. There is still alot of mystery.

Look at This cover page for Eikow the scope is so similar to a Swift 831, not exact but similar. Is it possible they had the same manufacturer using the same tooling? Yet different optics? Takahashi says they have been a manufacturer since the late 60's, why don't they include the early dates with Swift? Where they really Swift or just optical manufacturers that supplied Swift and later evolved into Takahashi?

These trademarks on this page are optical manufacturers only, did some of these manufacturers also machine their ota's? for example circle (t) they branded many of their parts with a(T), so my guess is they also made their own parts.

We shouldn't assume that all the trademarks that we see may be the optical manufacturer(we have all seen double trademarks). The second trademark could be the wholesalers or another manufacturer.

Look at Selsi, how many different trademarks do you see on their scopes at different times, sometimes they have HOC,APL,Astro.....yet some of us mistakenly assume the trademarks are Selsi.
Selsi Company, Inc. is an Importer/wholesaler home page


We see brand name scopes with the same trademarks but different parts, and sometimes we see the same brand scopes with identical parts yet different trademarks. I think that SOME wholesalers DISCLAIMER:Not all used a mix and match of manufacturers probably based on price or availability. And these brands are confusing the heck out of us 50 years later.

Lots of questions and mystery.

Good find Steve, i think you are correct.

On this Tasco there is absolutely no maker's mark. Rather unique in that respect along with being rather spartan. Hey I'm damned lucky the plate is still there and in good shape! Mike

Hey Brian,

Yep. This list needs to be a guide. It amazing that we are talking about just 50 years ago and there is so little accurate information.

Also, just a quick update...member CUIR sent me some images of a Circle K eyepiece. Thank you! I say it is Kenko. Ha!

Back on the first page of the thread you identify a mark as one of the marks used by Astro Optical, and call it "Type 1". Later on that page, you show several scopes apparently bearing the Astro Optical "Type 1" mark, but designate them as "Royal". Are the marks subtly different, or am I missing something else, like Astro Optical later became/merged with/etc. Royal?

Thanks,

Jim

Here is one Keith just posted.

Hiroki (Galakuma) in Japan believes this is also Takahashi. Further research is being done.




This one is quite similar to those marks on the original orthoscopics provided with my Vega. They've got the lazy 8 (infinity) symbol stamped on them, but no oval around it. Any ideas? Circa 1960.

I think I can finally confirm the BOL symbol even though I have to admit it is not what I thought it was. It had been suggested in earliar posts that BOL might have stood for Bushnell Optical Laboratory but knowing that David P. Bushnell sold telescopes that he "got of the shelf" as he put it I doubted that he would ever use the phrase "Bushnell Optical Laboratory" as he never actually manufactured anything. But as I later found out he did use "opticians" in his California shop to do warranty work so I am guessing that gave someone the idea and viola, Bushnell Optical Laboratory Inc.




I have to correct myself on this one after reading something from David Bushnell. In it he says "BOL was one of those manufacturers over there" referring to Japan and then he goes on to say he could not remember which one! We may be back to square one with BOL.

I just came across a new symbol that I don't remember seeing before. It is a diamond with "OTC" inside. Anyone know who that is?




Oriental Trading Company IIRC.

And the, Diamond Z-Zanzutsu (sp?)

Circle Z is better than most anything you can buy today, but IMHO inferior to Royal, Yamamoto, Eikow, etc.




Hey Steve,

The Diamond Z is the symbol for "Tanzutsu".

has there been a discussion thread on the quality of these optics???
I'm about to rebuild an entire scope from a lens and focuser set.To be honest I don't have a lot of money to waste, so Id like some input on whether a Towa lens is worthy of doing this.

Maybe I missed this one KO I found it on Celestron branded Ortho and Kellner oculars from the late 70's.

I have a 25mm volcano top ortho with a "Made in Japan" sticker and "NS" printed on the side of the black top section. It came with a 1973 Cave I just purchased, but don't know if it originally came with it. Anyone know what NS means, and the eyepiece's source?

Thanks,
Alex

I think it's KD and I believe they also did optics for Vixen... but not sure if I got that one right. I have an old 60mm 910mm with this symbol on the focuser label. Awesome performer!

I thought I would revive this thread as I picked up a couple .965 EP's that have a Circle W on them. Anyone seen this?
