TEISCO

In 1946, Mr. Atswo Kaneko and Mr. Doryu Matsuda founded the Aoi Onpa Kenkyujo company, makers of the guitars bearing the Teisco and other trademarks (the company name roughly translates to the Hollyhock Soundwave or Electricity Laboratories ). The Teisco name was chosen by Mr. Kaneko, and was used primarily in domestic markets. Early models include lap steel and electric-Spanish guitars. By the 1950s, the company was producing slab-bodied designs with bolt-on necks along with guitar amplifiers. In 1956, the company name was changed to the Nippon Onpa Kogyo Co., Ltd. - but the guitars still stayed Teisco!
As the demand for guitars in the U.S. market began to expand, Mr. Jack Westheimer of WMI Corporation of Evanston, Illinois started to import Japanese guitars and amplifiers in the late 1950s, perhaps circa 1958. WMI began importing the Teisco-built Kingston guitars in 1961, and also used the Teisco Del Rey trademark extensively beginning in 1964. Other Teisco-built guitars had different trademarks (a rebranding technique), and the different brand names will generally indicate the U.S. importer/distributor. The Japanese company again changed names, this time to the Teisco Co. Ltd. The Teisco line included all manners of solid body and semi-hollowbody guitars, and their niche in the American guitar market (as entry level or beginner´s guitars) assured steady sales.
In 1967, the Kawai Corporation purchased the Teisco company. Not one to ruin a good thing, Kawai continued exporting the Teisco line to the U.S. (although they did change some designs through the years) until 1973. Due to the recent popularity in the Teisco name, Kawai actually produced some limited edition Teisco Spectrum Five models lately in Japan, although they were not made available to the U.S. market (Source: Michael Wright, Vintage Guitar Magazine).
