Yes the famous 543, wish I still had it. And balanced on the toe clip.
This was the frame that I later converted by fitting the Paris Roubaix ends and gear system actually rode it in the Weston GP, with 14 to 24 and 47x50, using Campagnolo HB control front changer while the right hand undid the wheel, having to pedal forward to change, in a bunch that hastily allowed some space.
And they think a minimal crack in an alloy head tube is life threatening.
Generally my winter bike had my Q/R dynohub in a fiamme 14 ounce rim.
Frame by Queree Brothers Birmingham, with large brass letters brazed on the top tube.
