OBO. Cash Only! The same one I saw bought by American Pickers as they sought to add original equipment to their rebuild of the building that housed an auto dealership and mechanics garage from the 40's/50's ish. (Sorry low on specifics there). I know this comes from a "Gas Station" which had the big "Dino" Sinclair sign out from on the N/W side in Chicago. Mr. Carson was my Dad's best friend... when the station closed, he got all the Atlas engine testing equipment (now long gone) but I kept this. Mr. Carson showed me how to use it. Dad brought it to his garage when the station closed in the 70's... I've had it in storage since 1998 when I cleaned out my dad's garage. All the glass is clean/unscratched. I'd imagine the gauges work (light sensors?), but not been used (AFAIK) since I last was shown it. If you know what this is, then you know you want it for your garage, man cave... collection??? More than happy to take serious collectors to go see it in person...located in storage at Elston and Armitage. Viewing available between 10am and 8pm. Email me your inquiries. Too many *fools questions here, but give your info I'll reply.
