I do wonder if the early 3- and 4-speed blocks might have been narrow enough to do that flip, however.

Frames are built symetrical, so flipping the wheel would still put the tire in the centre. That's why the wheel is dished. All that needs attention is the chainline; whether to use the inside or outside chainring, or go to something else altogether. I do know that if I try a 5-speed or compact 6-speed freewheel on the straight thread of my Brampton hub, it extends past the locknut. But that's because I have track rear spacing (110mm) on my Jeunet. I'm sure the Brampton hub with a 5-speed block in the freewheel side could be flipped on the Raleigh GP.
