I firmly believe the metal of this type was either of better quality or manufacturing technique than the later larger diameter cranks. Look at the revolutions the cranks were taken up to in the early Seven racers. Like many others here, I would also replace it with one the same diameter.
I was going to say "bad luck" Chris - but then if it's broken without taking out the rest of the engine it's arguably very good luck!
