That's a Spanish-built CASA fighter built by taking the 109 fuselage and marrying it to the Rolls Royce Merlin engine. The reason why the Daimler engine wasn't used was because none were available (apparently the Messerschmitt 109 production license extended to the frame, but not the powerplant).
Czechoslovakia also had a license to manufacture 109s, and some of these found their way to Israel during the Israel-Egypt conflict after WW2. On some models, the fat-paddle blade was used for the propeller, and I've read reports that said that it was a dog of an airplane to fly. The Daimler engine rotated in one direction (counter-clockwise?) so the airframe was designed with weights off-set to counteract the torque from the Daimler engine, but when the Rolls Royce engine was used, it rotated in the opposite direction (clockwise?) which wrecked havoc with the weight distribution and flight characteristics of the aircraft.
So, yes, its a 109, but only past the engine mounts.
