-JdK- A photo found in an old copy of "Motor" and in my biased opinion one of the best looking Carroll-CS1s ever! Specs include a three-stay frame, heavy-duty TT Webbs, 8" Enfield hub rear, probably the 7" Horton hub at front, 20"/21" wheels rear/front, positive-stop Sturmey-Archer box without kickstart, Lucas KS1 magneto, straight-thru pipe. Carburetter probably an Amal and fitted horizontally in the conventional 1920s manner, not a flange fitting. The licence OF9502 was issued between May 1929 and April 1930 in Birmingham. All of which suggests a works special.
Surprisingly, the OF9502 licence featured on these pages before but on a very different Norton (below)! The pic comes from an article in The MotorCycle and in the caption suggests it used to be Woods' bike and that it was crashed into a van. Looking at the differences (note the frame and downdraught cylinderhead), about the only thing these bikes seem to have in common is the numberplate... and the CS1 above seems to be the earlier one.
