I recently purchased a cycle, serial number T22134,which I believe is a 1932 CCM. On further strip down, I have found another number on the forks, BSA13/16H, not sure what this means, Could anyone help explain this number?
BSA stands for Birmingham Small Arms, an English armaments company that diversified into bicycles circa 1880, to maintain financial solvency during times of peace. They quickly became a major player in the British cycle industry.
In addition to manufacturing their own bicycles, BSA supplied components, tubing and frame fittings to a number of other manufacturers. I'm assuming the stamping is actually 13/16G, in which case G stands for gauge or the thickness of a piece of metal or tube. 13 gauge and 16 gauge were typical thicknesses used in a fork's steerer column. Often steering tubes are thicker (Ie. a different gauge) at the bottom to provide more material where it is brazed into the crown.
BSA was a known supplier to CCM. Their multi-speed hubs were options on CCM models for a number of years.
