Thanks for pointing me to the Armstrong-Siddeley engines
I think it is a 14 cylinder Tiger.
I therefore stab at the AW-19.
recall that:
AW-19 doesn’t have a cross bar between the wheels.
perhaps a Fairey IIIE with ferret engine. Or a Fairey Seal or Gordon but it doesn’t match the AS panther engine which was normally fitted.
