EELCO Gauges

Anyone know stuff about this EELCO gauge. Age and what not would be helpful. Is it worth it to try and sell it?

 

I've got an oil pressure and an amp gauge. I got mine out of a junkyard so they were cheap. They don't pop up often and guys want them pretty bad. I'd like to find a temp gauge but I'm not holding my breath.

according to dad, (60 this year) it looks to be from the 50's and might be for a 6 volt system. as far as value goes, it's worth whatever somebody's willing to give for it. for a base price look on ebay and see what thier going for.

 

The same gauge is listed in the 1965 Honest Charlie catalog.

 

hmm I didnt see them on ebay so I thought I would ask here. I found it in a rambler wagon with some funky aftermarket ignition. the guy was probably trying to get the most MPG outta the old inline 6.
