Quite a lot of 20s cars had cast Aluminium number plates. Obviously the foundries must have had a "slot together" pattern set to make all the different plates quickly in period. But making a "bespoke" wooden pattern at home isn't too difficult. I made this one for one of my cars from 4mm plywood.
Any local foundry that does Aluminium castings should be able to cast them for you.
