The company received orders from the Royal Canadian Navy for 12 motor torpedo boats, including the prototype, from the RCAF for 6 70-foot high-speed launches and 6 40-foot armoured target-towing boats, and from the Royal Netherlands Navy for two batches of 8 70-foot motor torpedo boats.
The second Dutch order was the last received by the company and was completed in the summer of 1942.
[2] Four of these boats, were reverse Lend-Lease and became US PT 368-371 Of the 12 Royal Canadian Navy boats, only the prototype saw service in Canada, designated CMTB-1 before all twelve were transferred to the Royal Navy in 1941 for service in the Mediterranean.
Unable to persuade the Royal Canadian Navy to purchase more motor torpedo boats, the company retooled and spent the rest of the war using its factory (specialized for building plywood boats) to produce parts for de Havilland Mosquito bombers.
Scott-Paine sold the company in 1946, the basin at the plant was filled in but the factory still stands today.
