A warehouse overstock store I shop at occasionally still had an elevator operator when I went there last year. I have no idea how that old freight elevator to the electronics department on the third floor passed inspection.
I know of four elevators in Dallas that were installed 80 years ago and still going. The controls drawings in the machine room were last revised in 1936. The elevator inspectors seal in stuck on the corner of the slate backboard which holds all of the relays.
I have pictures someplace.
