Never noticed a closed car with front suicide doors until now.
I believe the change over on the Coupe door opening position was between 1923 and 1924. 1923 open from the front and 1924 open from the rear. Someone correct me if I am Wrong....
Michael you are correct -- suicide front doors on the coupe/coupelet from 1915 to 1923 (all low cowls).
Hinged from the front 1924 model year to 1927.
Several makes used a suicide front door on the closed cars see: https://en.wikipedia.org/wiki/Citro%C3%ABn_2CV
1908 Model S Ford Coupe (about 28 produced - suicide style).
Below is a 1934 Ford -

If any American marque made an ugly car in 1934, I haven't seen it ! My favorite Ford V-8 year !
I'm guessing the main reason for suicide doors in most cases had to do with considerations for strength and ease of construction. In the case of the '34 Ford, with that swept-back angle of the "A" pillar, it would require a fairly complicated swing-out strap hinge to keep the door level as it opened - the "B" pillar was vertical, so hinges could be simple ! ( and cheaper !)
