Otis Series 1 freight elevator with vertical doors!

Surprisingly found this peculiar cargo lift with vertical doors, (I think) metal Lexan buttons and green segmented indicators seen on the Otis Series 1 model!
IN EXTRA FOOTAGE: Sadly, the passenger lift has already been modernised by Lift Hub. It was previously Nippon Otis.
Location will not be disclosed as it is a factory with hearing protection required (it is LOUD to an unbearable degree) and only authorised personnel can enter the working area.

Those metal lexan buttons are often seen on older UK made OTIS lifts in the UK. The passenger lift might've been originally Nippon OTIS judging by the door tracks and bumper.
