I believe the first engines using spark plugs as an ignition source were made in 1902 so if it is that's a pretty neat and historic find. I'm not sure what 1902 plugs looked like though. What do the letters above "1902" say?

I wonder if it’s from a boat motor? I know most are thinking a car?

Very nice find Casper

No, don't believe it's that old. Maybe 1950's give or take a decade. Real early plugs had smooth porcelain sides....no ridges.
