Hi Mike,
I rebuild a lot of vintage engines, and must say that crank journal size at Standard do not commonly appear as "rounded off" measurements. I have the 1945 Morris Commercial C8 workshop manual and no where in it can I see crankshaft dimensions, although it does list the two undersizes available.
I suggest anyone removing bearing shells to carefully check the numbering on the back of the shell to determine what undersize it may be (or even STD).

When measuring crank journals always check for ovality too, when determining if they are worn.
