Ultra could hv mispelled IV. for 4.KG54, but first the II.KG54 was not in the area at that time , second it gave the Kz B3+.U , third if you want to write a book , I submit you the Malta-case it could revealed some surprises.

Other possibility, some crews with their planes in stage at Grosseto, could hv the "chance" to test their new knowledge

But interpretation of message heard by the brits could also be wrong
