It’s 4 meters long - over 70 calibers. It’s a different shape at Soviet 57 mm guns: antitank ZIS–2 and tank ZIS-4 (rare).
We tried to find information about close versions of Ordnance QF 6-pounder 7 cwt gun /Valentine tank gun or 57mm Gun M1.
I’d like to get sizes of British/US 57 mm round, including max diameter of cartridge.
Any ideas about the gun itself?

linnet,

I have some fired 6 Pdr 7 Cwt cartridge cases which I could measure, would this be useful?

linnet,

I have just measured a fired 6 Pdr 7 Cwt cartridge case with the following results:

Length: 440mm
Rim Diameter: 90mm
Rim thickness: 5.9mm
Head diameter: 82mm
Shoulder diameter: 71.5mm
Neck diameter: 59.2mm
Mouth diameter: 59mm
Shoulder height: 360mm
Neck height: 410mm

Remember that these measurements are from a fired case, dated 1942 but they should be good enough to assess whether that barrel is chambered for this cartridge.
