M3 (Lee, Grant) Medium tank variants

Riveted Hull.

Aberdeen Tank Museum
The welded hull eliminated the possibility of rivets breaking off inside the hull and flying around when struck by an incoming round.

Cast Hull
This hullcasting has no side entry, a later variant than above. That is one very large chunk of cast steel. I guess it would go on to the machining process next. I'd like to see the mill they used.
