OK so it's a 3-bearing splash-fed crank. I'm not sure but in the top photo it looks like the oil pipe union has been blanked off? And as you say, no pipework to the usual location on the centre main. Which brings me back to my question above, is there any sign of a drilling into the oil gallery next to the oil filler neck? That being the most likely alternative lubrication arrangement (for the C/M) I can think of.

There would be a plugged hole somewhere around here:
