Hot Rods ID help Tachometer

Here’s what I know. It is from the ‘64-‘66 era. Maybe a JC Whitney item? I have a ‘66 JC Whitney and don’t see any like it in there. No small print around face. “Solid State” puts in the 60s for sure. Brushed aluminum cup. Thanks.

 

That looks close to one I had on my 64 Galaxie that was sold by J.C. Penny.

 

RAC

 

Is that said with certainty & authority? BTW-thanks

 

Reminds me a lot of RAC

 

I looked at it and immediately thought Sears for some reason.

 

I guess I asked because I googled pics of RAC. Nothing came up even remotely close
