96100, when the factory paperwork was raised, did not have a Distributor assigned, so presumably was built without an order being received, which is unusual.
That remained the case until April 2, 1985 when it became a factory-direct sale, to customers Robert T & William J Healy.
Was actually sold on July 16, 1985, to Air Charter Services Inc., of New Gretna, New Jersey.
I am not aware though of any Model designation that was scheduled for the proposed 1200.
