"Wrinkled glass" bulb or smooth?
 

Need to replace a headlight bulb on a September 1929 original
unrestored Fordor. Would like to use as close to factory correct as
I can find.

Restoration Guidelines show wrinkled glass up to early 1929 but not specific for later production. I'm thinking smooth for the later ones??
Any help would be much appreciated.
