The Monarch-engined Battle was sent to Wright Field for evaluation, and flew 250 hrs while there.
The very same as in the picture above of Fairey Battle I K9370 (for the spotters). The Fairey P-24 engine was to be put into production by Ford in the USA to power the P-47 Thunderbolt, but that didn't happen, obviously. One of the Monarch engines survives at the FAA Museum at Yeovilton.
