Technical What is this thing????

I bought a box of miscellaneous parts the other day. These were in the bottom of the box. For the life of me, I can't figure them out. What say ya'll?

 

Horn contacts would be my guess. Goes under the center cap in the steering wheel

 

Wheel hub static surpressors maybe

 

They look like the spring loaded battery terminals in a flashlight to me.

 

NOS , Seat cushion springs !!!

 

Yup that's exactly what it is. Lots of late 40's and early 50's cars had them under the bearing caps of the front wheels. Suppose to help with static on the tube type AM radios of the day.

 

Found this under bearing cap, 45 fin Buick drums I bought for RPU. A couple years ago.

 

that's what static suppressors usually look like, they're quite a bit smaller than those shown. Maybe they're for big trucks? with radios?
