Hi RS&J, As I'm sure you are aware, Scott Bonnar literature; especially
pre 1960, is pretty thin on the ground. Until your friend and compiler of the Scott Bonnar History made that available, virtually no information on the early years of the Company was to be had.

It still remains very difficult to date a machine
exactlyI, personally, have no manuals, brochures or literature prior to the 70's.
Sorry I can't be of more help....at present!!
