S/C engine FC 3060

In 1999 I corresponded with Pierre Trachsler from Suisse. He told me that he and his father in 1953 bought an S/C engine FC 3060 and some other Cord stuff from Charles Deschaux in Paris. He was interested to hear if this engine was the original engine from #32051-S now with Citroen-engine and owned by a museum in Denmark.
But according to "The Timeless Classic" the original engine for #32051-S was FC 2806, so my question is - from which Cord came the engine FC 3060?
Does anybody know the serial number?
