brass body sort of like a lamp on a car but much deeper, thought maybe some type of tester adapter but? no numbers or lettering that I can see.
so fire away
one thing they are not
Are they the same diameter or does one slide over the other ?
they're the same
The spring looks like it contacts something, like the springs in battery operated things, flashlights etc.
How springy are they?
Chilly
I can see the dimple on both, does the other have a slot also? do they line up with each other or offset? does the springs come off? or are they secured from turning? with the dimples & slots looks like they should slide on another piece with matching slots & pins. (since they don't slide on each other).. maybe a toilet paper roll holder?
like a wimpy spring?
sort of look like a lamp socket but why so long? they don't look like they have been used.
Light socket should have the center spring insolated from the housing & a bayonet slot to lock it in.. can't be electrical...
agreed, it's weird! that is why I posted it. just can't recycle them!
