M. Horabe Guitars?

Anyone have experience with M. Horabe classical guitars? I've been researching them, calling around, emailing... just looking for people who know anything about the history of these guitars, their construction, how they sound. Several people I've spoken with over the phone who have them have said they sound fantastic. This is basically what I know:

• Handmade in Japan by a group of luthiers under the name M. Horabe
• Sold in Nashville, TN, in the 60s (?), 70s and 80s.
• Distributed by JTG of Nashville
  • They still exist, but according to their website they only sell kids toys and educational items
  • (I tried calling them, but their mailbox is full and their other number redirects to some BS about hearing aides)
• 2 series in a catalog, the Signature and Recitalist series. Signature was the top-end series.
  • Signature: Models 70 and 50
  • Recitalist: Models 30, 30S, 20, 20S
• Several other models in the wild, listed on the internet
  • 25, 35, 40, 60

I've purchased a Model 60 and I'm just trying to figure out how rare it is, the year of production, the construction of the back/soundchest (if it's solid or laminated rosewood).

I'm excited to get it in my hands and hear how it sounds for myself. If anyone has any information or experience to contribute to this topic, I think guitar players everywhere would benefit.
