Kalle sent me some excellent photos of his Strat to post here:
 
 
 
 
 
 
 
A lovely guitar, in fantastic condition for its age! Unfortunately I can't say exactly which factory made it - but there are some interesting details which might give some clues.
The first thing which strikes me is the neck construction - it's made from 3 pieces of timber, as far as I can tell alternating plain-sawn & quarter-sawn pieces. This was very common on better-quality Japanese instruments, to make the neck more resistant to twisting.
This sort of construction appears on many Matsumoku & Fujigen Gakki models - but my feeling is that this guitar isn't from either of those factories. While this guitar has the Gibson-style nut common on those, it has truss adjustment at the heel end. Mats & Fujigens with this type of nut would usually have truss adjustment at the head end, often with a small plastic trc.
The skunk stripe is also interesting - I don't think I've seen a 3-piece neck with this feature before, and it's purely decorative on this guitar, as the fretboard's separate and the truss rod would have been fitted that way.
We have a plain neckplate, with an MIJ sticker - this I think confirms it's not from Mat or Fujigen - and means it's probably not from Rokkomann or Moridaira, since all of these factories are associated with particular plate styles.
Kasuga used plain plates, as did Tokai (whose early 70s output is associated with Kasuga) but there were many other factories producing instruments of this quality, so I really can't be very specific about who made it.
Anyone else got any ideas?
Jon.
