Despite it is not an Horological item this Inclinometre was part of the kit together with the other measuring equipments including the famous watches used by the U.S.C.E. in 1944 and has kept since in a perfect shape.
It was probably used during war and I tought it was worth seeing it.

I'm leaning in that direction also.

Hi Enzo. You have a very nice instrument in excellent condition. Small instruments like this were sold in military surplus stores in the US up through the 1960s or 1970s.
