Koban, #12276


This is an open flywheel battery ignition rowboat motor made between 1917 and 1919.

The model letter designations were year specific. For instance, in 1917 this model would have been a Model E. In 1919 it would have been a Model G. This serial number, # 12276, does not conform to any existing schemes that identify years by serial number.

So, any date or model I can give you is only a guess.
