Interesting necklace; looking for ideas on when, where, who?

This necklace has me stumped; obviously not antique but vintage at least (I think). I am hoping that someone may recognize the maker by the design style or at least help me to identify when it may have likely been made and where? I am coming up empty; I thought this would be fairly easy to identify due to it's uniqueness but No. Would this be considered Modernist, MCM, Machine Age, something else? Maybe an (anonymous) artisan one-off? It is very well made, not sterling (thought it might be stainless steel but it is only very faintly magnetic); measures 16" end to end; the central drop is about 1 3/4" top to bottom. No marks of any kind anywhere. I actually really love the looks of this piece but when I wear it I kind of feel like I'm wearing a necklace made of pull tabs. Thanks for your thoughts!
