I have a cylinder head from a Merlin engine and it has a number of Irving 10 spark plugs in it
The internet says this plug was used in land speed record cars with aircraft engines but not in ww2 aircraft can anyone help please

This is half of one of the Vs got the other half. Only info I can find is that this spark plug was designed by Phil Irvine for 1929 land speed record car 'golden arrow'.

Spotlessly clean casting but filthy springs and corroded bolts. Has someone cobbled this together for display I wonder?

Here are pics of an original plug from a Hurricane with Packard merlin 29:
