NavList:

Hello all,

my dad recently acquired a 1983 Tamaya MS-733 SPICA with "Univision" full view horizon mirror and 4x40 scope; wrench, spare bulb and scope shades were in the plastic case with the batteries but alas no manual... 

The current manual is available for download on the Tamaya site at https://www.tamaya-technics.com/e_site/images/pdf/manual/sextant_e.pdf 

However, it doe not include information on Univision. Also, for my own research into historic Tamaya products, I would like to see the specifications table in that manual with details of the MS-933 Venus, comparing it with MS-733 and MS-833.

I would be grateful if someone could share scan or pictures of that older manual here.

Yours aye,

Al Stewart

PS: I had done some searches of the NavList archive regarding the MS-633 sextant, which regularly turns up on ebay. It is still shown on Tamaya's Japanese-language website and catalog / brochure, my best guess is it was not produced for their export market. The MS-633 appears identical to the older version of the MS-833 Jupiter with ladder frame, more economical model with black-finished aluminum plate on the arc, and sold with the 7x35 scope. Two sub-models, MS-633-4N and MS-633-4L appear to come with 4x40 scope instead, and have only 2 shades each for horizon and index mirrors; the -4N model has no illumination.
