1957 Front Turn signals both out

[OhioTbird]

Just got the bird out of storage. Neither of the front turn signals work. Rear blink fine.
Am I looking to replace one fuse or two bulbs?

Thanks in advance.

Do the parking lights work?
There is no fuse

Could also be a dirty turn signal switch.

With mine
It is usually the ground side
If I remove the bulb and reinstall it
usually starts to work

weird. Now driver side works. Passenger side out.

I'll first try a bulb.

Put some dielectric grease on the bulbs before re-installing them.
