Beautiful looking car! I understand your dilemma because I agonized over putting front turn signals on my '37 Packard. It was built without turn signals at both the front and rear.
The lights that special-k suggested would be my first choice because it would be most appropriate for a car of that vintage.
Second choice would be some type of motorcycle light mounted on short stanchions slightly above the bumper.
Third choice would be the headlight/turn signal combo. Even though it would probably be the simplest route it is also the most modern looking option. It would look out of place on an otherwise stock looking vehicle.
On the '37 I couldn't decide, so I left the front turn signals off...
