Italian Gun Sight - Need Help In Identification

[semovente]

Hello all, I have an Italian gun sight that I can't seem to identify. There are no date markings that I can find on it all or a nomenclature. The fabrication of the sight and its storage case appear to me to indicate WWII but I'm just not certain. I have attached some pics and I would be grateful for any help. Thanks.

Hello, I do not know the exact name of the model, but in wartime images can be seen placed on artillery Model 65/17
and Model 47/32.
Missing the lower part that allows to insert the lens on the cannon.
