Hi, Hutch here been a while since I've been on the Forum but just came across this one with my neighbor it's a univac UVM 902 m and I was wondering does anybody have any information as far as what this is and about what year it was made? Definitely looks like it was industrial application and it has a removable power head that can be used to vacuum and just simply expel stuff outside I would imagine not sure. All I have right now is the top side picture of the hook up I can add more later.
