This bomber operated on the Bf109 engines? Weren’t those fighters?
The famed Merlin engine powered the Spitfire, Hurricane, P-51, Mosquito, and the Lancaster bomber. Wright and Pratt-Whitney engines, of the same types, were used in both fighters and bombers by the US in WWII.
and the Merlin engine was selected to replace the Daimler-Benz engine in the Spanish Air Forces versions of the ME-109 and the Heinkel 111 bomber.
BF109 or ME109 (same thing) was a single engine fighter and a good one. Using four of the engines to make a bomber makes sense.
