Research on Restoration of Big Binocular Telescope
Well, the program rushes into the further super-deep world.
I would like to introduce Shigeki Terada's report as follows.
Shoyu ... It is the very fundamental seasoning for Japanese
and it is their major part of "taste of Mom's cooking".
Regionally, there are many variations of it's taste.
The taste of Kyushu region (southern part of Japan)
is sweeter than usual one,
suitable for the "Sashimi" of southern seafoods
or pork cookings (Kyushu specialty).
Choko Shoyu K. K. is a major shoyu house of Nagasaki Pref. Kyushu.
Established by the name of
"Nagasaki shoyu and miso brewery union"
in 1941 at Nagasaki City.
This report is described about the binocular telescope
they are keeping for about 70 years.
Shigeki Terada, Nikon Kenkyukai's Telescope/Binocular researcher,
found a report about this binocular in a website.
This Japanese article described that very old big binoculars
were at the Choko Shoyu factory.
Terada requested the lending of
the binoculars to the Choko Shoyu headquarters.
Terada's purpose is a research of the old vintage binoculars
and a complete full restoration.
Kindly they accepted this proposal,
and they sent this precious specimen to Tokyo.
Terada took this to pieces completely,
cleaned and repainted over 6 months.
Now, this is the rare chance of study of the dismantled
historical big binocular telescope!
Shigeki Terada who begins explanation for members
Completely Dismantled Binocular Telescope
Nikko Made Fork Mounting (Re-painted)
After peel out its old paint, name plate is found.
This is "Enomoto kogaku seiki seisakusho"
(Enomoto Optical Instruments Works) 15X4 10cm 70degree
high view angle binocular telescope, product No.2011.
May be produced in 1939.
Enomoto Kogaku is established 1934, now merged with Fuji film (Fujinon).
But, strangely, the fork mount is made by Nikon, product No.3925.

Beautiful Roof Prism and Rhomboid Prism
Luxurious big 70deg. Roof prism and Rhomboid prism
there are writing of product No. and L/R sign with pencil.
Now, Terada is explaining about his work
I want to put some comment about paint analysis for this.
Original paint color was IJA (The Imperial Japanese Army) gray
same to the Nikko binocular telescope Mr. Hayashi brought today.
Which still remained on eyepiece case behind diopter adjusting ring.
And there are little residue of same colored
fake leather painting (including cork powder)
on main tube and prism cases.
But re-painted with spray gun carefully soon after it produced
with IJA brownish-deep green color.
This modification is recalled this binocular is applied
not for on the vessel but for on the ground.
In WWII era,
there were many antiaircraft gun base around Nagasaki city area.
This binocular may be set on such base.
Or, because shoyu and miso were controlled materials during the war,
this binocular may guarded the factory of Choko Shoyu.
But, if it was, those base and factory was in the 2km area from Ground-Zero,
The damage of A-bomb may have been unavoidable.
However, there are nothing about such damage on this. Is it miracle?
As a mark of respect this matter, this time,
the color of re-painting was done by carefully adjusted color
and gross of original IJA brownish-deep green color remained
on the objective part dressed tube covered the outer hood.
After this restoration is over,
re-introduction will be held on Nikon Kenkyukai again.
This binocular surely show us the super clear image same as that former days.

Big Vintage Nikko that Revives in Great Britain
I would like to introduce Mr. Yukikazu Hayashi to you.
Yukikazu Hayashi, old big vintage binocular collector,
lived in Britain long for his business.
When residing in Britain, he collected a lot of binoculars from the world.
He is enjoying the living with binoculars because he lives in Japan now.
Hayashi explains the following.

It seems one of the models
that became the origin of present Porro prism type binoculars.
Carl Zeiss Jena 8x24 DELTURIS FOV:8.75°C.1925
Erfle eyepieces that Dr. Heinrich Erfle

Barr & Stroud RANGEFINDER FT27 80cm C.1918
The rangefinder of Barr and Stroud was installed
in the bridge in battleship Mikasa
that had won Baltic Fleet by Battle of Tsushima (C.1905).
It repaired in Nikon afterwards,
and it exists in an intimate relation with still Japan
that exceeded 100 years in an optical technological field
of Barr and Stroud (present Thales).
It is a same type installed with WWI also by the vessel
of UK Royal Navy though the photograph is a product
after ten-odd years.
Nikko 15x105 WWII binoculars (with 60 degree inclined eyepieces)
The product used for empire naval forces vessel
to watch aircrafts under observation.
The crack enters around the right mount axis of the main casting body,
and then it has separated.
It was fortunately succeeded in the restoration by the hand of
Mr. Antony L. Kay, OptRep that has being worked on the repair of binoculars
with over 50 years in the United Kingdom,
and it finally revived.
Refer to the material of the Tokyo meeting for a technical analysis of
the binoculars in October, 2010
when Mr. Shigeki Terada is doing the research report.
Big Nikko as Beautiful as Goddess
There is a sense of existence in stately dignified
and oxidized silver.
It is likely to have concentrated on the technology
that raised the performance until the detective device
such as radar spread because it was thought
that the performance of binoculars had greatly influenced the battle.
Yukikazu Hayashi who explains about big vintage Nikko
Mr. Antony L. Kay is a world famous repair engineer
of vintage big binoculars.
The following gentlemen is Tony-san.
I took this photograph in Britain.
Tony-san is not only a specialist of the binoculars repair
but also a writer of the book on the technical research.
The two volumes are called 'Turbojet' by Antony L. Kay, published by
Crowood Publications, being the early world-wide history of the turbojet.
Volume 2 has a section on the Japanese history.
Other of his books are called
'German Jet Engine and Gas Turbine Development -1930/45',
'Junkers' and 'German Aircraft of the Second World War'.
