This is an original 1937-55 Chevy Truck Extra Cooling 6 Blade 18 Fan. Pretty good condition, solid, some dings/small dents, some lite pitting in areas, couple blades may need some minor straightening-see photos. The diameter of the center hole is approx 1.
Center to center of the mounting bolt holes is approx 1 5/8" next to each other and approx 2 1/4" diagonally. GM Book shows this fits'37-55 Chevy Utility Trucks (also shows note about fitment on'37-38 trucks)-see last photos for pages in GM books for reference. Will also fit smaller pickups if you wanted extra cooling.
Correct for trucks with a 216 or 235 - 6 cylinder engine -Not for 261. May also fit cars, but would need to make sure there is enough room for an 18 diameter fan.
