Reason I thought Flyer is that this bike (and the team) went to the Olympics so I would have assumed the pure track racer rather than the road racer frame. Also the cranks, though supposedly not original (and why is that the assumption) are not cottered so would also indicate the CCM Flyer bottom bracket. Look on the headset for CCM stampings; as clubman said the frame number should be around the seat post/lug though may be under a lot of paint.

here’s my Road Racer (38). Note the cottered cranks and the fork ends (if you can see them)
