Merci beaucoup!
Many thanks to share these fine pictures with us.
The 7" set in the center of the picture showing Mr. Tezuka
is a Nippon Columbia TV-1/1953 from Kawasaki.
I have the same.
My experience with this man is not as good as yours.
He asked me for a source of early transistors in Germany.
I searched, get from him an unfriendly reminder and after I did
find a company received no thanks from him.
On the other hand I asked him for some knobs and schematics
for my japanese radios and TVs.
Never get an answer on this.
He is just the right kind of guy we need in our hobby.

As far as I know he is president of the japanese radio collectors club.
Bien cordialement,
