I can't make out the trigger shifter in the picture. Looks like it might be a window 3 or 4 speed. The first reference for that shifter was from this ad in December 1949. If that is a window 3 or 4 speed, that would place the bike forward to around 1950. Pretty sure the seat tube transfer with the model name on this bike was changed by 1951 to the model name on the down tube.


the older style
