Question about Savoia-Marchetti SM.79 Sparviero Data Plate

[procpilot]

Hello!

I was directed here to ask a question about this item: a data plate for shock absorbers supposedly from a Savoia-Marchetti SM.79 Sparviero - the bomber workhorse of the Regia Aeronautica.



Apologies for the picture quality. If you need better pictures, please mention it in the comments.

I am wondering two things about this plate:

-Could we tell if this is from a Savoia-Marchetti SM.79 Sparviero? If so, could we tell which variant it came from? The Italians made a few versions of this plane after all.

-There is a number to the side: 31274. Could this be the serial number of the plane? I looked up surviving Savoia-Marchetti SM.79 Sparviero bombers in the world and it seems to match the numbering: 24327, for example - https://www.airhistory.net/photo/171382/MM24327.

Unfortunately, sources for the Regia Aeronautica are scant in my country, so any expert assistance would be appreciated. Thanks!

Serial Numbers of Italian military aircraft (MM matricole militare) were usually applied or stenciled on the exterior rear fuselage. If a serial number or a part number was printed on a plate it usually referred to the part itself, for example on engine plates. But here are the MMs for the S.79:
