It is thought that a Telescope(OEG) begin
to be used when it was Type 91 fighters and
probably this sight was domestic production.
The production company was a Tomioka optic
machine production place and was producing
the sight etc. of a cannon in addition. It
is made of the Tomioka optic in all of an
army and navy.
Japan is getting Ju88, Fw190, Bf109, Me210,
He100 etc. Ju87A-2 that the Japanese army
imported from Germany in Showa 13 to, start.
The sight of Revi-2b, ReviC/12 C, ReviC/12D
etc. were attached to those bodies. Also,
I should be obtaining it after that regarding
a Revi16 sight. The sight of Japan is receiving
the influence of the sight of Germany fairly.
However, the influence of the sight of the
Allied Forces, especially America are big
in the war last stage.
