Vintage capacitor replacement

I’m trying to find replacement for this vintage capacitor. I’ve attached a photo below. It powered the motor of an still camera from the late 1960s.

The stamping reads:

Sprague
500 MFD 320 VDC
RED POS
D36783
6708

The dimensions are approximately 1.75” x 3.1”.

Do you have any recommendations? Thanks.
