1968 Sno-Trek SC-1

I recently bought a vintage sled from a guy in Moose Jaw, Saskatchewan, Canada. As far as i can tell it is a 1968 (Possibly "Aktiv") Sno-Trek SC-1. It has a 277cc SACHS motor with an HR-8A Tillotson Carb. I have been looking for some more information on it and specifically an owners/service manual that is in English. Imperial Oil (Esso) sold these i believe. It is very closely related to the Swedish made Aktiv Sno-Tric SC-1 which is slightly easier to find info on and seems to just be the American version of that sled. I have found a couple old imperial oil brochures with some info on the sled but if there was ever an owners manual that is what I'm mostly interested in.

This is from a plate riveted on side of tunnel
Manufactured by AB Westeraskmaskiner, Morgongava Sweden
TYP - SC1 Nr - 7711164

Thanks and any help is appreciated.
