1940's Vintage PP-3610 Atlas Sound Mic stand w/round cast iron base.

This is, according to the Chicago History Museum, a 1940's Atlas Sound, now AtlasIED, Chrome mic stand with a round cast iron base that has two recessed lines going all the way around on the top of it. It is a model PP-3610 and has the amazing serial number 1, though it has been disputed that it wasn't what the number 1 above the model number meant, though no one also could not to give an explanation good enough or a better reason why it was there. AtlasIED says the serial number is stamped on the bottom in the exact place it's at but would not confirm it without actually being able to see it themselves, but said if they were to take a guess, with no liability on them,, that it was the serial number and was the first of that model off the line, but again, wouldn't confirm it without physically seeing it themselves. They said someone could've put it there and they wouldn't know without comparing the marks. I only know what I'm told. It's almost $60 to ship I'll take care of myself
