Bri asked
Was it made by the Canadian Car & Foundry at Fort William, Ontario ?
Peter M Bowers states in his book Curtiss Aircraft 1907-1947 published by Putnam that:-
The US Navy foresaw interference with it's own production at Columbus,so the Army versions were built at the Curtiss St Louis plant and subsequent orders were on Army contract.
and
With the Curtiss factories being unable to meet the Navy's increased requirements for the still unproven SB2C, additional production was assigned to the Canadian branch of Fairchild Aircraft Corporation which built 300 as SBF and to the Canadian Car & Foundry Company which built 835 of an initial order for 1000 as SBWs.
