I tried editing your photo but still couldn’t make out the numbers. It’s too blurry.
Canadian and US built Johnsons used separate groups of numbers. Hence the Canadian motors, with lower production numbers than US models, will always be numerically lower than US built models of the same year.
Here’s a list of serial numbers for Canadian (Peterborough) built motors followed by a list for US built motors.
Not sure what the trouble is, looks perfect from here.
The numbers are 71856 (and what looks like a “-” dash) (or a space) then a “1”?
I will edit for sizing and resend from my computer.
If I’m right, then I might have a ’48 according to the chart. Dors anyone know of any other differences that would help tell us?
Thx!
