I think I could categorically say they are not canam & not english. Can am ran only 35mm forks in straight lforks (axle on bottom of slider). Likewise the english. Canam never ran 36mm forks & I'd be nearly as certain about the british.
Seems to me theres little/no doubt they are Jap; kayaba not showa (again, I'm fairly sure honda/showa never ran 36mm forks)
