Unknown model 2
The guitar shown above may well be a Matsumoku model - it pre-dates the known models (1981 on) and has the same logo as the Matsumoku acoustic guitars.
There are some very similarly shaped guitars, also branded as Westone (Different logo) which are definitely not Matsumoku instruments. The one below is one of these (Thanks to Dick Zoeteweij for the picture)
Generally, if the logo is in italic script, it is not a Matsumoku instrument
This logo appeared on guitars (Like the one above) that were made in Italy
This logo appeared on an old banjo that was apparently made in Germany (G.D.R)
