Vac Fans
The bearing plates and fans with center hubs all seem to be Electrolux from 50s-70s.In picture 3 the left & right fans of top row and left of bottom row are the early 1205 that combined the rear fan spacer onto the fan and should not be reused as they went back to separate spacer after problems with these.These seem same as first 3 in top row of picture 7.
Other fans may fit most Lmnb type motors.
Others can add more to this.
