Dan;
  I don't think that there are that many if the Toronto plant followed what they did in Philadelphia, probably the power line cap is a Bakelite block but not much else. Most of the Canadian models shared chassis with their U.S cousins up until 1939-40, though the cabinets differed sometimes, like my model 3118B. They are not really that had to restuff if you have to, Mike/Morzh has the technique right down.
