Technical Early Ford Transmission Identification

I was wondering if anyone could identify this for me. Its close to an early V8 but not quite. Thanks!

 

Yeah. Early V8 Fords were round in the front as I recall.

 

Definitely a 41-42 case for a Commercial vehicle with the G series flathead six

 

Thank you!

 

Pretty sure I have one of those too. Guts same as V/8?

Guts are swappable. But different tooth count

 

Different ratios? Better or worse for V8 use?

Thanks,
Dave
