Quick scratch or poke with a pin or knife point will tell you if its lead or not.I would think it's iron or lead . I would imagine as heavy as it is it's not lead but I could be wrong
As it most likely was beforeIt's lead after I scraped it

Hey nice to see you posting, I asked in a post months ago if anyone had heard from you. Glad to see you're still kickin.Thanks Nathan. I think I am finally back on solid ground. Good to be back.
HA! It looks like a stogie!Found this near an old barn today. It's heavy AF for its size. First thought was a weight of some sort maybe ? I don't think it's a roller bar
