Italy has a long history of using Webbing. The Regia Marina bought Mills Patt.1906 webbing
back in 1907, for its Fanti di Marina ( "Marines") and Armed Landing Parties.
This continued thru WWII.
Initial lots were made in Britain, later lots woven and assembled in Italy ( Venice Naval Arsenal)
After WWII, with Britain partially re-equipping the Italian Army with SMLE and Patt.37 webbing, Italy used its experience with Mills type weave and assembly to make their own, with variations as seen.
Btw, the 1906 Mills equipment was very similar to the 1923 RAF pattern, and the later 1937 pattern...only the 1906 used 3- clip ammo pouches ( like the Non-Infantry P.37 types -- two pocket unit each side.)
As an aside, the RM also used a canvas sling for their TS short rifles, also a Mills design.Leather didn't last at sea or in the tropics.
