Hi Ray,
Has anyone ever heard of "Cycles OK" ? In 1962 and part of the '63 season, I raced in kermesses representing that frame builder from Antwerpen. The frames were lugless and made from straight gauge Reynolds 531 tubing. The tubes were mitered and silver soldered; then fillet brazed to create smooth flawless joints. The lightest bike I'd ever seen at that time. The builder, Johan, also experimented with using heavier down tubes (3 cm) in the top tube position. The idea which is common today, never caught on at the time. I sure wish I had mine today.
