This is a Delco Remy 6 cylinder distributor assembly from a 1960 or 1961 Chevrolet Corvair flat 6 cylinder.  It takes a different cap , rotor and points than 62 and later distributors and is pretty much all by itself.    The number is 1110256 and the date is 0 B24  It  turns but the advance mechanism stuck and needs oiled and worked..  The vacuum advance diaphragm holds vacuum for awhile but doesn't move the rod.  There is a degree segment stamped into the point plate which I tried to show in the last photo.   Free shipping, usually same day.
