Armoured Snowmobile manual

Great pictures Ed !
Looks like I may be wrong about plywood crew covers...In " Design Record", vol 8 (Army Engineering Design Branch) it states " To minimize crew exposure due to the open top hull, two man-hole type flat plywood covers were installed over the drivers and observers seats. The front cover was hinged to the body of the vehicle so that they could be folded out of the way when not in use. Although of simple construction and easy to operate, it was found that the crews movements were somewhat hampered when the covers were in the closed position" . I don't know enough about military protocol to know if this was recognition after the fact or whether the plywood top was officially sanctioned and promoted.
Most of the 410 built were converted to close bodied machines. This was done in Ottawa at Ottawa Car and Foundry ( think that correct) and I have a couple of unpublished photos of the new machines with their numbers on the assembly lines. B.P
