It’s one of the many “ names “ that Yanagisawa used in that period so that they could cover different markets.

the same sax existed also in the version without Prima, unlike the Elimona , which seemed to mark a special excellence, series there is no particular significance in the use of these names.

Yanagisawa also sold lots of stencilled horns under a plethora of names and for different makers

 

Prima Gakki was/are one of the Japanese distributors for Yanagisawa.

 

Interesting

Nikkan Gakki was the original company which, when it was split, gave origin on one side to Yamaha Wind instruments (they only had piano’s before) and Yanagisawa on the other

 

Yes , the Prima indicates a sax to be sent to Prima Gakki a Japanese wholesaler of musical instruments. Back in the day, Yany had lots of different labels and brands and markings on (mostly) identical saxes.

 

Thank you for all your kindly replying.
I searched the keyword "PRIMA 楽器" in Japanese and found a website which is the official website of "PRIMA YANAGISAWA", the link is as below:

Thank you all again, now I know the relationship between with Yanagisawa.

 

To my knowledge, after the 80's, Yanagisawa 'Prima' horns run in the same serial number sequence off the Yanagisawa factory line, ie, Primas have normal Yanagisawa numbers.

 

It's usually happened in the world that adding a distributor's logo on product, we call the business model is "ODM".

 

Who is "we"?

I'll ask about your TLA in another post.

 

Yes to the serial numbers.
