Looks good, great progress.

I always wondered if these 'Hybrids' where actually built like this front the arsenal or where they field modifications "rebuilds, repairs' done to salvage usable parts from tanks. Just really seems like way too much work for a factory to mate a cast front to a welded side and rear hull.

They did. Chrystler and alco locomotive works made them.
something about the metalurgy of the cast armor being stronger than the sheet welded armor.
yes lots of work to build. But, maybe it was faster to cast the front and weld it to a body than to have to weld and fabricate the front. Especially on the early small hatch shermans where the front slab could be as many as 5 or 6 pieces of slab and cast hoods.

Makes sense. I know many crews believed the curved cast hulls gave them a little more protection by the possibility of a shot glancing off it instead of the straight angled welded frontal armor. still just seems to be a fabrication / manufacturing nightmare.
The fact that the homogeneous cast armor had slight differences in its metallurgy than the homogeneous plate probably gave them some weld filler metal issues too. Can't be sure but it is always a possibility with specialty alloys.

it was more a cost/speed of manufacture issue...the cast front was cheaper to produce due to the man hours involved...the smaller section meant that it could be produced in more foundries as they could be smaller than the ones needed to produce a whole hull...
