On Facebook marketplace a while back I came across a guy trying to sell what he called an, "antique WWII era mortar canister," for $200. As a former US Army artilleryman I recognized it as NOT that. It was a propellent charge canister for 155mm howitzer, and very clearly marked with a manufacture date in 1990s. I messaged him about it, and even sent a link to another listing where a guy was selling the same things by the pallet load for the same price. (Big army base nearby, so such things pop up all the time.)
The guy never responded, but did drop the price to $100. Another week later I got curious, and he'd finally changed the listing to be slightly more truthful, but the price was still $75.
I honestly think the guy BELIEVED it was what he originally listed it as, and he probably bought it as that himself, otherwise he wouldn't have persisted for weeks. Scammers tend to close up shop and run as soon as someone calls their bluff.
