47 x 328R Italian anti-tank

[Tony Williams]

Hawkinson's Big Bore Ammunition lists include an Italian 47 mm AT gun case with a bottlenecked case 328 mm long and a rim diameter of 62.2 mm. From elsewhere, I have a projectile weight of 1.5 kg and a muzzle velocity of 820 m/s.

The problem is that I cannot find any reference to this gun or ammunition. Hawkinson lists it as the "47/40" but as far as I can make out, that designation is for an improved version of the usual 47/32 Böhler AT/infantry gun, featuring an L/40 barrel and probably longer-cased ammo than the usual straight-cased 47 x 195R (Hawkinson lists an Italian 47 x 235R M35, the Böhler case length also used by Austria).

Can anyone comment, correct or provide any information about all this?

Thank you!

Edit to add:

I have some follow-up questions, concerning the 47/32 (Böhler):

I understand that the Italian version of this used a 47 x 195R version of the cartridge, but Hawkinson also lists a 47 x 235R (the Austrian length) in his Italy section. Is this true or an error?

Was the L/32 the only barrel length used by Italy (there seems to be some confusion over barrel lengths and designations, with L/40 being quoted for some?

Tony, in my knowledge the only case lenght for italian 47 mm A/T guns is 195 mm.

During the war, a 47 mm L/48 A/T gun was also developed, but it never entered service .... born old.
I don't know its case length.

Cannone controcarro da 47/48


Only one other gun was often used as an anti-tank gun, the 65/17 regimental gun.
Otherwise field artillery was used.
