I don't see a hand crank, perhaps he has a later engine with starter and generator.
The hand crank is definitely missing. To me, the clothing and photo in general looks older than 1919, which would mean there was no later engine with a starter and generator available yet. If I'm right it would suggest he has an accessory commencer. I've only seen photos of them, but they are a linkage set-up that enables the engine to be started with a pull of a cable handle inside the car.
Henry, Here's one of two different pull from the dash starters I have in our collection.
Here's my other pull from the dash starter.
Aftermarket combination starter/generators that included lighting systems were available prior to 1919. The starter/generator was mounted in the engine compartment and chain-driven off the crankshaft.
I have one of the devices that Eric has described. I also have one of the pull handle units
I would bet that they have the electric one.
A few years ago I built a bolt on electric starter using a one wire alternator and a Subaru starter (because it turns "backwards"). It incorporated a cog belt drive to replace the pulley
I'd like to see a picture of that two headed photographer!
Here are a variety of combination starter/generators:
Here is a system where the starter and generator are separate and driven by belts instead of chains:
Aside from the lighting, I find the car's windshield interesting. It folds forward like. '13, but the car is clearly a '14. The doors give that away. The front fenders have the mid year and later crosswise bead and front bill.
....'bout the biggest cowl lights I ever saw!
