In 1974 Maurice Summerfield, an English guitarist and great connoisseur in the world of jazz guitars, was producing his own brand of Maccaferri-style guitars in Japan by Kiso Suzuki importing them to England under name "CSL Gypsy". Two models were offered: D-hole and O-hole with 12 fret necks.Nous'che Rosenberg of Rosenberg Trio (www.rosenberg-trio.com) used a D-hole CSL guitar on their first record "Seresta" (brazilian equivalent of "get together") recorded in 1989 with no overdubs and co-produced by my friend Hans Meelen ("ears that hear everything")from http://members.fortunecity.com/gbowlds/jm-imac.html
