No, the hole distributor compare to groove at the end of plunger is laid out has the reverse, the plunger ''R'' and the plunger ''L''  to It  mirror one of the other.

The keyway that indexes the plunger to the camplate is indexed differently in relation to the distributer slot on a left hand rotation plunger/head, this is what Tintin is referring to.

I took a photo on an old seized 12mm (''R'' rotation)

Look at the delivery port location alignment compare to the filling groove at the top of plunger.

And look at the filling port on the sleeve of the plunger.
