I just got this fun find, this cool little blower I have no info on other than it has metric threads, and VD cast into the bearing cap on one end. It's about 9 inches long 7 inches wide and the ports are about 1 3/16 inch. Has a tapered shaft with keyway slot on one end (pulley end) and a flat blade drive on the other end (tach drive?). It was/is polished and factory engine turned bearing/gear cover. I'm thinking it's english, maybe a old kit blower for an MG or who knows. Any ideas? I've got a few flatheads sitting around that this thing would look great sitting on.
