I haven't checked, but a 240V capacitor should be even smaller.

240v RMS, the voltage peaks are much higher and the cap needs to be ac
rated.

It would be. I didn't bother stating "AC" again for the 240V capacitor
as I had made clear the original was 440V AC.

A three phase motor would not have needed a start/run capacitor.
Likely, one single phase motor has been replaced by another. Perhaps
the original was an ac/dc type motor.

Were there many 440V single-phase motors around in 1966? It just seemed
an unusual combination for a fairly low-power device.
