Mike:

I'm scanning through the Specialloid piston catalogue while eating my
dinner, and there are plenty of 4" bore pistons in there, the biggest
problem seems to be the small gudgeon pin diameter and the compression
height (centre of gudgeon pin to top of piston)

Waukesha, Reo, Federal, Fordson, Hercules and many more have them, but
I see your biggest problem being with the small wrist pin size,
followed by the compression height.

I'll  keep on looking and will shout is something near comes up.
