Cannone da 75/46 C.A. modello 34

The Cannone da 75/46 C.A. modello 34 was a mobile Italian anti-aircraft gun used during World War II. The designation means it had a caliber of 75 mm, the barrel was 46 caliber-lengths long and it was accepted in service in 1934.
History.
Showing the influence of contemporary Vickers designs, it was a sound and orthodox design; however, its production was first late in starting and slow in being carried out (by 1942, of the 240 ordered only 226 had been delivered). This meant that older and obsolete AA guns had to be kept in service even though their efficacy was minimal, and also that its production was parallel to the newer and better performing Cannone da 90/53. In addition to the mobile modello 34 a static mount the "Cannone da 75/46 C.A. modello 40" was produced. Once again production was slow and only 45 of the 240 ordered were delivered.
Assigned both to field units and to battieres protecting the Italian territory, it was also used on the Eastern front and in the Tunisian Campaign as an anti-tank gun (in which capacity it was also fitted to the Semovente da 75/46 self-propelled gun). Its performance was considered good in both roles, especially in the latter, with its AP shell that could pierce of armor at ), but it was never available in numbers.
After the Italian Armistice, the Wehrmacht captured some of these guns, and employed them with the designation 7.5 cm Flak 264/3(i), while modello 40 guns were given the designation 7.5 cm Flak 264/4(i)
