GB Forestry are a wholesaler, so you'll need to order the part through one of their dealers.
The Canadiens were one of the better saws of their day, and were imported to Oz by Mobilco Ltd in the 1960s. Their agency ended in around 1969, when Skil Tools bought the chainsaw division of Power Machinery of Vancouver, BC.
