Both of these have scrolls, but one uses a narrow rod and one uses a
wider rod. The one with the narrow journals has heavier webs where
the crank transitions from the main journal out to the rod journal,
whereas the one with the wide journals has less material (the metal is
less bulbass). Any ideas? Joe(B)

1147 and 1296 cranks are the same up to 71, post 71 1296 cranks can be
identified as they have a larger nose. Early (small) cranks have a scroll
type rear oil seal but they can all be interchanged with the relevant type
of rear oil seal housing.
