Don,
I'm not trying to nit pick here, I just wouldn't be a grognard if I wasn't concerned about these things.
You guys have put together the best WWII OOB I've seen.
The front turret armour on the Cromwell I is currently rated as 6 but apparently it should be 8.
Here's a quote from my source:
The Cromwell's armour was generally rolled homogenous plate, initially the hull front was 64mm thick, the turret 76mm thick and the turret sides 64mm, some sources list the turret front as only being 64mm this is most likely due to them forgetting to include the 12.7mm carbon manganese backing plate attached to the front 64mm of rolled plate, in later versions this was a single plate of 76mm thickness.

This is an excellent website BTW, lots of useful info.
The Cromwell I icon is 125 if that helps.
cheers,
Cross
