Have a Kasuga Dreadnought, Model No D-350, Serial No 6340, where 634 is in black ink and 0 in red ink. Bought it used early to mid 1970s in Copenhagen, Denmark. Paid next to nothing for it. Everybody laughed at me and looked at it as being a joke. Only thing I have had done through the years is grinding down the frets a bit two years ago at "30th Street Guitars" in Manhattan. Must be solid wood, because it sounds exactly like a Martin D-35, which is about $2500 these days for a new one. I cannot thank Thor and Odin enough for my beloved Kasuga. Kasuga is my friend. Many, many songs came out of it. Will never get rid of it.
