T. Haruo Guitar

I have a T. Haruo T100 six string. I purchased it new in 1984 from Kline Music in Sacramento for $450, it retailed for $750. I have replaced the knock off tuning heads with locking Sperzel gold tuners. I think it is a great guitar, great looks and wonderful sound. The fingerboard inlay, the three piece back, the cedar top. I have been looking for more information on its builder and material, etc... I didn't like its feel until I put light bronze strings on it about 6 years ago, it always sounded good. At first glance most guitarists think its a Martin, I think it plays better.
