BIKE ... i am prone to CONSIDER that each Chief badge variation came from different batches running concurrently ... like you suggest ...
and GARY ... i am in accord with you, in that you are one to prefer more evidence from ad literature.
Admittedly, my self-acquired license to deem a Chief badge Early or Late is based solely-upon the Architecture Of The FACE of the Chief ...
in comparison/contrast to dated sales literature.
Color scheme AND variation have never really been a consideration of mine, to date a Chief badge, until maybe a year ago (+/-).
Am adding another consideration ... i would like to have documentation (from original Chief bicycles) .. of ...
1. Pertinent information from the bottom of the crank hanger ...
2. Photo documentation of the front and rear of the badge ...
3. Photo documentation of the debris-field behind the badge, and that which may still be clinging to the headtube.
MUCH MORE RESEARCH is needed, before a conclusion can be reached.
