WESTFIELD COLUMBIA FRONT SPROCKET VARiIATIONS



Usually the front sprocket encountered on Columbia's is a 'Sunburst' style but I have noticed a 'Heart Shape' variation on several bikes.
This odd sprocket was observed on bicycles with Serial Numbers MG134319 (Mark Chapin's Collection), MG138969 (Mine), MG143313 (Alexis Salomé), MG145375 (Airborne Museum, Sainte-Mère-Eglise, France) and on MG145642 (Gustaaf Desmet).
Initially when I restored my bicycle, I suspected it wasn't correct for a WW2 specimen, but seeing it on other bicycles and on at least one WW2 period picture leads me to believe that roughly 10.000 of them were in fact manufactured that way.

The second pattern (heart shaped) front sprocket is clearly visible and the bike is equipped with a bell and toolbag attached to the saddle.
 
Location and time of the picture is not known but the soldier wears WW2 style Herringbone Twill uniform with cold weather 'Blucher' boots.
