Primarily Petroliana Shop Talk Forums Shop Talk Petroliana Forums General Petroliana Discussion Unknown 1950's-ish service equipment cart info?

Originally thought this bottom cart was a match to the Huot top box but then realized it's not. I still love it. I had an old sun cart with similar slots for a piece of equipment in the top.

It's got matching red plastic torpedo type handles if that helps.

Any ideas on maker, era etc?
