At last I have found people who are aquainted with Yasuma instruments !!

I hope that someone can shed some light on my Yasuma Mandolin.

I bought this instrument secondhand in 1976 and I estimate that it was no more than 5 years old at that time.
It is marked K Yasuma ( in fancy script) and Newance on the headstock. Inside it shows Nagoya, Japan.

This is a lovely instrumet and it plays very well ( especially with a set of Martin Strings).

Any information would be very much appreciated.

Thanks.

Gaetano
