Up for grabs is a rare mcculloch m39 flathead supercharger. In great condition with original paint. The unit is nice a tight and ready to run. Still has original red paint. It comes with original generator bracket with idler tensioner; however, the idler is broken and would need to be welded. Most for sale don't even come with this bracket. I also have a pair of dual groove water pumps for it. Very nice unit. Asking $4500 usd plus shipping, but interested in offers. For more info or pictures, send me a message. Cheers, Breakdown
