Rick's Euro

I have this old Porsche/VW crank shaft. I have had no luck in identifying it. I have included several pictures (along with pics of any markings/numbers). Please note the tapered end and the 'sleeve' that slip onto that tapered end.

Anybody have any idea what this goes to?
356???
912???
914???

Any help would be GREATLY appreciated.

I don't think it's 356 or 912. Could be 914?
