This is a pretty weird model, I've never seen one besides this auction.. It's been listed forever, I put an offer in months ago and they didn't accept it.. I really like these Marvin fans, perhaps I'll try again..

Do you have any idea how old it might be? It looks like it could be 80s or 90s? The casing kind of reminds me of a Duracraft from the back design with the slots. It could even be from the 2000s. I seem to recall seeing the twin versions at some time in the 2000s era. Plus Marvin stopped making fans in 2007, or 2008 and the last ones I recall I think were the screen fans that were kind of a brushed nickle color. They still make the window screens and rainguard louver screens but no fans with any of them.
