I have searched the Nishiki topics here several times to find general and deeper answers and information about the two Nishiki frameworks Professional and ONP.
I only found one or two pictures and texts from the owners.

My questions:

-Were there publications or brochures from the manufacturer with data and details about the frames for the presentation and market launch of the two models?

- in which years were these two frames produced by Kawamura?

- Was the frames produced only when quantities were ordered by the specialist dealer(s)?

- Were both frames only offered in the USA or also in Europe?

I know, maybe too many questions. Nevertheless, thanks for answers.
