Post war the Merlin 24T formed the basis of the 500 series that found its way into the Spanish built CASA CA2111
The 2111 was fitted with the Merlin 500-29. Also the HA-1112 Buchón (Merlin 500-45) and Fiat G.59 (Merlin 500-20) were powered with transport versions. One story I read was that RR had a stock of 500 series in preparation for airline production that never came to fruition, Spain and Italy thereby were able to obtain cheap deals to power their fighters and bombers.
