Hi
Does anyone know if or what model Douglas these flywheels are from.
They came in a box full of mostly 2 3/4 parts. Obviously they don't suit a 2 3/4.
Thanks
Brett

Brett,
Don't know what they are from, but definitely not any model Douglas ever made.

P.S. Any relation to Wade camshaft family?

Thanks Doug
I didn't think it was off a Douglas bike.
No relation to Wade Camshafts that I'm aware of.
cheers

Numbers cast into both flywheels are "150 20 D", one side has an "A" the other has a "B"
The distance from crank centres to the conrod pin is 2.0"
It doesn't appear to be for a twin, more likely a big single, possibly BSA WDM20????
