One change on the 42 is they stopped rolling the rim late in the war to save production time.

The 42 is an example of cost- and time-cutting that resulted in an acceptable substitute for what preceded it, but some of the surviviors really show that the new production method was stretched pretty far- shells whose blanks were obviously not lined up with the dies, shells whose steel "wrinkled" where the visor had transitioned to the side flare (or striations over other parts of the shell), and their affinity for rusting.
