G'day wce,
That one could well be a 'stripped Automatic' - i.e. one that has had the Automatic front/rear throttle control flaps and associated bits removed. It certainly has the [busted] extensions of the front and rear axle housings, that were unique to the Automatic.
That would be because, back in the day, a common quickie method for removing the flaps was to just whack the flap pivot shafts with a hammer...
Have a close look at the carby top - the Autos had two throttle cable entries there.
If your machine actually left the factory as an Auto, one will have been plugged, if it's there. The Auto handle plate is a fairly strong indication, that this was likely the case.
