I've seen one of these before but cannot remember what it is. I thought it was a 2-pounder but I haven't found anything that backs that up.

Length: 105mm
Diameter at base: 39.1mm
Diameter above the shoulder: 36.7mm
Weight: 770g
Width of rotating/driving band: 15.8mm

Nevermind...I think it's just a 40mm L/60 bofors without the ballistic cap. I feel dumb.
