Ventilation Fans

 Was pleasantly (not really) surprised to find this medieval-looking piece in the parts horde.  I thought I had tossed it.   Is it worth attempting to restore?   Not really, at least, not yet.  Many use motorcycle rad fans, or for closer-to-original (something) add the type 65 squirrel cage/snail fan and shroud.   .

The stock fan weighs 34.1 ounces, (less dirt, plus missing blades) has a 6" diameter blade, and the 3 equally spaced mounting feet are on a 7" circle.  This unit from American volt looks like a good choice to replace it.

The rest of the vent parts are in good shape and a box of spares is in reserve.  Need to clean those hoses though…
