Does anyone have any information on which Japanese framemaker made these bikes in the 1980s? I am fairly certain that they were imported and sold by an American company based in Seattle. I also think they were made to that company's designs and specs, (as was the case with brands like Centurion, Lotus, Nishiki etc...). I just can find any information on who made them. They seemed to have used primarily Tange tubing so I do not believe they were one of the many brands made by Miyata. Any information or thoughts would be greatly appreciated.

Thanks.
