At the risk of being pedantic, it's worth noting that Yoshi Konno wasn't hand-building these frames. He had a staff of builders working for him, which included Koichi Yamaguchi as the master frame builder from 1983-1987. So, it's more accurate to say they were made by 3Rensho, as Jim said above.
Portlandjim Did Konno design those early Allez & Sequoia frames? Or was he building them to Specialized's design? I had thought Konno designed them, given his use of the iconic offset fork crown, but you'd know better than me.
