Mystery engine shaft ?

[OZZYCB]

Just wondering if anyone would know why there is a machined shaft/spindle castings in the lower cases at the bottom right side of the clutch (inside the clutch housing area.) The curve on the lower r/h side of the clutch cover allows for something.Seems the cases were designed for something ??  anyone else picked up on this? 
sorry couldnt figure out how to upload a pic..

I had noticed that too. No idea what it's for either and I think I remember asking about. I do recognize the engine.  That's my E100! It sure looks better now.

my guess is that maybe they originally intended to use it as an oil pump drive driven off the clutch basket,  i checked the die cast cases i have laying about and there is no provision for it, although the space is still maintained ,.,,another sandcast oddity
