Firstly, the exhaust manifold isn`t from that engine, it is from a Jumo 211, you maybe already knew that! If you have a photo of the other side, Hurricanes have a chain sprocket on the hand turning gear whereas Lancs have a tapered alloy extension casting. Looks like a Lanc bearer to me, but some Mosquitos had Merlin 21s that were converted XXs and these retained the original ID plate, and have a very similar bearer. All 3 types could be fitted with the Hydromatic prop shown in the pic.
Probably a Lancaster.
