Can anybody tell me the manufacturer and age of this sheet metal roller please?

Found this in storage at work and looks like it's been forgotten for years. Been kept warm and dry so in pretty good nick. Doesn't look like modern kit, so I'm guessing it's quite old but not sure how old. Don't reckon it'll go back into service but seems a shame to leave it in a store room indefinitely. Any ideas anyone?

I think it's probably mid 20th century based on the nice curvy cast legs, a nice thing and still a handy bit of kit with the grooves at the handle end for rolling bar!
