I own a gun safe a bit larger than that, though it’s modern so it likely weighs less and has no wheels. I had the safe company deliver it after purchasing it for an extra $200. Two guys showed up with a pallet jack and some plastic skids. Worked like a charm.

When we moved we paid the moving guys an extra $150 to move it. Four very strong mid-late twenties guys with shoulder/forearm straps moved it. They were worn out but got it done.

You’d think it would be worth something as scrap metal by its weight. Anyway, good luck.
