Am hoping someone can help identify the following projectile? I came across while scouting a disused rifle range - the range was commandeered by the Dept. of Defence during WWII and used as a training ground for Australian & possibly U.S. troops. As it was also a public range before and after the war, it's always fun to collect all the differing projectiles laying about and wander around in the hope of stumbling across the odd cartridge, although I've also found the occasional parts of 2 inch mortars (pieces of fuse housings, tail fins etc) in the area, so was clearly used as a mortar range during the war as well. The item pictured has me stumped, though...it was quite heavy for its size as you'd expect from a large projectile & pretty heavily corroded. The main stand-outs are what appears to be 2 sets of driven bands near the base & a sharpened projection at the nose end which appears to run through the centre of the "projectile"...whatever it is, it was pretty much crumbling into dust due to weathering, and was left where it was found. Have searched through pics of everything I can think of that may be a match, although have come up trumps - I'm thinking maybe British/Commonwealth 2 pounder/40mm anti-tank gun projectile? Any suggestions??
