Thats a nice Box fan. I also bought a fan just a few days ago. Its a 100W Industrial Fan made out of metal. Its used for my Offgrid system to keep the garage cool. Still need to install it :D
You can find a lot of vintage things with the original box and papers on ebay. I have another with it's original box and papers. A Royal Prince 501 handheld vacuum cleaner. I'll have a video of that when I get it.
