Very nice Seba, looking at the pictures I was thinking what is this and man that is a thick casting and when I saw the ones after the lathe work it all came together. Does the cylinder take a liner?

looks like a press fit steel liner...

I guess those 4 bold holes hold the head on, I imagine they are connected to the steel?? o.O

Backside of the fins flat to make way for push rods?
