Are those bullet holes in the doors? Note also the bullet shaped lights on the front fenders. I would guess the car is about 15 or more years old when that picture was taken. Probably sometime in the 1930's.
Non-demountable 30x3 1/2 all around. They did add a battery though.
A 1917-18 that got electrified with a battery on the running board?
The ladies hats looks like what's seen in late 20's magazines, but it's hard to tell when a picture was taken..
Lol, it was a very different time. I don't think I know of 3 full grown ladies that would fit across the back seat of a touring like that now.
Those electric sidelamps look British. Why's it got the kerosene lamps as well?
And the wheels are demountable. Zoom in and you will see the hubs are converted to remove the whole wheel, there will be a spare wheel on the LH side. British again, used to cost £5 to have that conversion. Car is starter equipped, for a couple of years British cars were LHD until they redesigned the steering bracket to clear the generator.
