Astro Optical did not always use its manufacturer's mark. Here is a picture of the focuser from a 50mm Astro Optical Co. Ltd scope from the mid 1950s. This scope was also made for Bushnell and Micronta.

JamesE,

Did you notice that "Celestron" is misspelled on your 10X70 finder? That's a real conversation piece! I wonder how many of this particular finder were produced with this misspelling?

Preston,

That's the one noted above as Type 2. It is great to see the old Astro label on a telescope. Have you ever seen another telescope like yours with the full ASTRO?

Variation of the Circle Y? Looks like a Mercedes symbol. I am sure this one has been discussed before.

Logo belongs to this eyepiece. Still cannot figure out how to post multiple pictures in one post.

Hey Lew,

Yep, I did notice it when I first got it. I thought it was cool. Glad you like it too.

My take, is that this was a first run series for Celestron and APL. Now I thought I read that APL eventually got taken over by Vixen. Is that correct?

Cheers,

Well cool! I did not know I had done this previously. But, Now with PICTURES Looks like I missed Circle + I know I had a picture of that one, but cant find it. Anyone have Cirlce + ?

Circle Dash (minus) was confirmed by Sheldon a year or so ago as Carton. Here is one of David's EP's.

Here's a H.O.C. branded Selsi from the mid-late 50's. Unlike Clint's H.O.C. Mayflower with brass cell, the cell in mine is aluminum and non adjustable. If you see anything H.O.C. buy it. Their optics are superb!

What a great idea for a thread!

My two cents -

I had outwardly identical "Circle Dash" and "Circle V" 18mm orthoscopic eyepieces. The Circle V was noticeably superior in performance to the Circle Dash.

Here is a shot of the Tasco 9VR label with the Circle V mark.

Here is my Selsi that looks to be of the same vintage as Scott's but it is made by APL.

Wow Steve, great thread.

Here's a mark (diamond S.O) I asked about in the binocular forum - these are binoculars branded as Hilton, and they have the 'triple tested' label on them, which implies Bushnell.

Maybe someone will chime in on S.O. That is not one I am familiar with. Looks bushnell to me too.

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?

My Prinz Optics collection are either circle T (towa) or Circle K
the model 660 is a circle K (76.2 x 1250mm)
the model 500 is a circle T (60 x 910mm)
the model 400 is a circle T (60 x 700mm)
I seem to recall that the 100 model is also a circle K but cant find my pic that proves it.
