Looking for a replacement fan?

Know this might be a bit of a stretch but still wanted to check as occasionally Redditors come through in a pinch!

We just purchased a 1930s house; it has a furnace that vents in one location in the hallway. At the end of the hallway, there are circulator fans to move the air into other parts of the house.

The fans were Coleman, but have long since stopped working. We want to keep the bezels and swap out the fan (which is approx 7”). Any ideas?
