The 1957 seems to be in between those 2 being more curved then the right and less curved then the left.

I'm not sure this is correct. It may just be wear, or a slight difference between the cutters.
The way I date the crankcase, particularly those made before the starter spring groove in Mark's picture is this:
There are three differences
1. No oil groove inside the crankshaft bore.
2. An oil groove, but with only one access channel.
3. An oil groove with two access channels.
To know what I mean by "access channel" look inside the crankcase where the crakshaft enters the bore. You should see:
A. One small vertical groove. (at the 12:00 o'clock position)
B. Two small vertical grooves. (One at 12:00, the other at 6:00)
C. No vertical groove means no oil groove inside the bore.
The vertical grooves are the access channels that allow oil into the bore for lubrication.
