Derk,
That engine may or may not have a serial number stamped. The general Ford practice was to stamp the engine number on the top edge of the transmission rather than on the engine block itself. Carriers were an exception where the engine serial number was also stamped on the top flat of the engine block on the left side of the intake manifold near the rear of the block. Try looking on the flats on the top of the block either side near the rear of the intake manifold.
For your Canadian wrench roll, the marking you can see is SCYCO. The manufacturers name is the only marking I have noted on the wrench rolls I have seen. SCYCO is Scythes & Co which was based in Toronto. A company history can be found here:
