The only actual CF-103 that was ever 'produced' was a wooden mock-up of a MK. III Canuck with swept-back wings and a new tail. This is the only known photograph of this model, the date of this photo is unknown (so if anyone out there know's of the date, please let me know.).
The powerplant for the CF-103, had it gone into production, would most likely have been two Orenda 11 or 17 engines, as was in the Canuck IV's and V's, but since the 103 concept was based on the MK. III Canuck, it probably had Orenda 2 or 8 engines in it.
