This time it's Crankshaft bearings - more advice needed

I have the crankshaft out. It wasn't quite what I planned but hey! Having got this far I might as well keep going.



My crankshaft is marked BBBB & 11111. My conrods are 416A (1-4) and the lower crankcase markings are BBBBC. Can someone advise me on correct bearings before I plunge in.



It would appear that these cranks don't get re ground is that correct? If the journals are scored or otherwise damaged the crank is scrap?



As usual, all advice gratefully received.
