npence said:The Sweet heart sprocket was used on more then one brand of bike besides schwinn like Dayton, Colson and probably acouple of others I think there is around 4 different variation of the sweet heart and have to be an expert to tell the difference in them. But I believe this one is the correct one for this bike though.
I've got a 26" Colson camelback with a sweetheart, too. I think mine is also correct and would be happy to post a pic for reference if you wanted. Great scores, got to love a solid old Colson! Makes me really miss my Blister Tank/Flying Ace.
