Dear Michael, Going through the Claud Butler frame drawings and the closest drawing number that matches your specification is B1011; 73 x 73 angles, 40 5/16" wheelbase, 11" BB height with 27", 17" chainstays CtoC. Close clearances for 27" wheels. These drawings were used as a customer guide to anyone who wanted a bespoke (made to measure special). I reckon you might have a plain tube Super Velo or Allrounder built to drawing B1011. This is a guess lugless welded Claud's are a nightmare to identify. Best wishes Michael Butler Wistow, Huntingdon UK.
