Anybody know what this tach is and what it may be from and the value of this piece?
I took it out of a 70 442 mounted underneath dash. Looks to be in nice shape don't know if it works anyway to test?

 

That's an old 5200 rpm redline knee knocker tack, maybe $150.

 

Is that not a Pontiac piece? '64 maybe?

 

OK thanks for the info guys. I was told a 1960 something? It looks factory and it has a grey, black(with red stripe) and brown wire much like Olds wiring. There is a sleeve around wires with 6412886 printed on it. The body is solid metal and pretty heavy. There is an embossed number on top of mounting 6412773 if any of that helps?
