Where is the gearbox oil level and filler hole on Ducato 2,5TDi?

Took vehicle to local Fiat agent - very helpful chap and confidently showed me wher the drain anf filler plugs should be but was as baffled as I was as they could not be seen.
Anyone got any pictures please. Russic book does not help.

should be 19mm nut on end of gearbox or possibly big hex nut or if not plug near top of driveshaft on other side of gearbox. oil should pour out of hole when nut removed if not fill up until it does.
