Vintage Mallory 310 HP Super-Mag Magneto For Chevrolet; Mechanical Tach Drive SOLD. Thanks Very good original condition. Appears to be complete. It appears to spin smoothly, and there appears to be very little side play in the shaft. Untested as I don’t have any Chevrolet engines. I gladly accept your choice of PAYPAL, cash or check; I like paypal. Price includes shipping within CONUS. In support of my H.A.M.B. and GJ brothers and sisters serving our country, I am pleased to ship to APO/FPO addresses.
