Can anyone identify the real manufacturer (1 Viewer)

[Barbican1987]

I am trying to find out who were the original manufacturer of these binos.

Although they are labelled Monk Navigator I don't think Monk manufactured them. I think he imported them from Japan. Maybe an older model from Fujinon who allowed Monk to put his name on them. They look liked roof prism rather than Porros but I bow to any superior knowledge here!

Any information anyone would be much appreciated

JB-35 according to this photo of the underside of the hinge :

Raito Koki Seisakujo Co. Ltd. - Lite Koki Seisakujo Co. Ltd. according to this listing :

Maybe a manufacturer which specialised in robust, weather resistant roof prism models? The Minolta 8x32 Mariner is from same manufacturer :

Good condition, tested and is in good working order. Condition: Used.

Thank you normjackson that's very helpful.

My cousin has them for sale and I wanted to track down the original manufacturer. I suspected they were of Japanese origin. Thanks Peter

My Minolta Mariners are tough but also pretty dim.

I confirm that the 8x32 Minolta Mariner has JB-35 Japan marked.
It also has a worn out Japanese oval sticker.
Marked field is 7 degrees.

There are 3 uncoated surfaces, including one on the optical window at the front.
The other coatings are single and multi (possibly achromatic double?) coatings.

Mild pincushion and quite good optically, but I previously noted rather dim.

I think that the body tubes are one piece.

I should use it more.

Regards,
B.
