I found these in former Yugoslavia.
This is about 3 feet long, made of iron and very heavy. Some kind of machine-gun barrel?
Do the holes go all the way through? If so, not a barrel. Could be a heat shield but unlikely if it's heavy.
This is about 20cm long
This is a mortar. They don't have to be heavy, and the fins typically are aluminum or some lightweight metal, the weight would be in the head from the HE. Quite possible it's a training or dummy round, and if you actually have it, I'd hope that's the case.
Looks like some machine-gun contraption, according to the owner but he wasn't sure.
Pretty sure this is an early mortar tube/firing mechanism. Projectile would slide over the end, charge would fire down low near heat shield, gases would escape at top from holes firing off the round. That's all a guess, never seen one like this but it definitely functions close to that way.
