Basically, three-rail refers to any of the Herald-based gearboxes where
reverse is to the left and up next to first gear. The later single-rail
gearboxes have reverse over to the right. And yes, the arm does appear to
have a different part number as well, although offhand I don't know what the
difference is. Note that the two different part numbers are quoted for the
"Clutch Disengaging Lever Assembly"; it could be that this refers to the
entire assembly and that it is primarily the sleeve and bearing that differ.
That's not totally clear from the Spare Parts Catalogue, but that's how I
interpret it.
In my experience, the slave cylinder doesn't seem to make a whole lot of
difference.
