The subject of track and road ends has provoked a livelier discussion that I would have expected. Here are two photos which may be of interest.
Sylvere Maes was the winner of the 1936 Tour which was the last to be run without derailleurs. This picture shows him about to remount after changing gear. Interestingly, the caption is wrong since it states the he is about to change (va changer) for the descent, but it's quite clear that the wheel has already been turned since the chain is on a small sprocket while the larger sprocket is on the left.
I'm pretty certain these are forward opening drop outs.
The other pic shows the little hook (usually a nail head) on the right hand chainstay of a pre-war frame. This is intended to catch and support the chain while the wheel is being turned. This frame also has forward opening drop outs.
