Hi, I wanted to find the difference between to two types of Italian guns in service, these are the 47/32 modello 35 and modello 39, now every site I have been on does not give any real difference between the two models, but when I went on Jager Platoon their data is slightly different, so hear is what I have got; 47/32 M35 Elevation: -15 to +56 degrees Traverse: 62 degrees Barrel Length: 1.680mm Weight in action: 305 kg Weight in Traction: 315 kg Range: 7000m 47/32 M39 Elevation: -10 to +60 degrees Traverse: 50 degrees Barrel Length: 1.830mm Weight in Action: 330 kg Weight in Traction: ???????? Range: 9000m The shell size I have is 47x195 for both models and I cannot find the amounts made, except for 928 & 1.040 for the M35, nothing for the M39. Thanks and best wishes Yan.
Not sure, if you try looking at the Carro Armato M13/40 tank. It Mounted a 47mm gun which may be similar to what you are looking for.
Hi Poppy and thanks for the reply, I have looked through my data on Italian Tanks and found this; M13/40 - 47mm L/32 Model 37 (Ansaldo) Model 1935 (AP) Shell Weight: 1.45 kg (AP) Muzzle Velocity: 670 m/s Armour Penetration: 44mm @ 500m @ 30° M15/42 - 47mm L/40 Model 39 (Ansaldo) Shell Weight: 1.45 kg (AP) Model 1935 (AP) Muzzle Velocity: 900 m/s Armour Penetration: 57mm @ 500m @ 30° I think that the two guns fired different sized rounds too; 47/32 M35 - 47x195 47/40 M39 - 47x328 I suppose they both had Horizontal Sliding Breech Blocks and Hydropneumatic recoils. Nothing more so far, but I will try and find some more detailed stuff on these vehicles and their guns. Best Wishes Yan.
It was built in two versions, the first with semi pneumatic disk wheels, and the second (in 1939, from which the name 47/32 mod. 39) with improved barrel and suspension (in some series also electron wheels with celerflex semi pneumatics). http://www.comandosupremo.com/cannone4732.html
Thanks Pacifist, I have been on CS and even search through their forum pages, but nothing in regards to the data required. The M35 had a height of 0.60m and a width of 1.02m, I cannot find any data on total length of the weapon, but would the M39 have the stats as the M35 (height & width), there total length would be different due to the longer barrel on the M39, plus I cannot find any data on the numbers produced. Thanks for the replies and best wishes Yan.
I recall a 47/32 at the museo della fanteria in Rome parked next to a 6lb (that looks huge by comparison) if anybody is really curious I could try to take measurements. I believe both the Model 35 and the Model 39 used a rather weak round though the Italian wiki page of the gun gives a 47x328 for a longer barrelled gun (Mod 38) used in the M5/42 tank while stating the Mod. 39 was just the original gun with an improved mount for towing by vehicles, I don't recall any pictures of a longer gun on a field mount, has anybody got one? . Storia Militare did a number of articles on Italian WW2 gun production over the years so there may be numbers there, will try to have a look or there may be figures is some Ufficio Storico books. BTW the 47/32 was never meant to be an anti tank gun but was an infantry gun with a secondary AT role.
Hi Ace, them measurements would come in real handy, here is a link to the Jaeger Platoon Site, and it describes the difference between the Böhler and Ansaldo versions, it calls the Ansaldo the M/39, but the stats seem to point at the M35, it also says that the M/39 was not semi-automatic, which is strange. http://www.jaegerplatoon.net/AT_GUNS2.htm The barrel lengths are different for both the Böhler and Ansaldo; Böhler; L/39 (Dutch) AND (L/40) Latvia Ansaldo; 47/32 (L/32) …. Would this be L/36 if measured by US/UK standards? If so what would the 47/40 come out as, L/44 maybe?. Ian.
I also found two different round size for the Dutch Bohler. dont which one is correct, 47x185R 47X227R The weight was 356 kg AP & 5.46 kg HE Ian.
