And I need some help figuring out where it fits in the overall scheme of UO eyepieces.  This is a "Flat Top" style like the "Professional Series" and is supposed to be a 9mm Ortho.  I thought I had all the flat tops which include a 10.2mm, 8mm, 6mm and 4mm.  I have not seen this 9mm before.  The printing looks like the Professional Series but does not identify the design as Ortho or Konig.  Picture:

The lower barrel has a black "Made in Japan" sticker and a close look at 2:00 on the top shows some adhesive residue that looks like it came from a small N.S. sticker that I have seen on other UO eyepieces.  Does anyone have any idea when this was sold and if it was a precursor to the "Professional Series", part of it or just a random eyepiece of the time?

 

I have a couple of UO catalogs but nothing older that the 30th anniversary issue.

 

Thanks

Clay

As requested - side and bottom pictures:

 

Side:

Barrel is (I think) nickel plated brass - it is a heavy eyepiece for it's size.

 

Bottom, note how thick the barrel is - standard filters will not fit:

It is an interesting eyepiece to me anyway.

I have seen similar "Made in Japan" sticker on the barrel here on CN around month back, also UO on the top. I remember it since there was a discussion why to put sticker on the place which should slide. I am sure somebody will remember/find exact thread. BTW there too was stated the barrel inner thread does not accommodate normal filters.
