It has been pointed out how good that I look with egg on my face, I am happy to oblige!!

Has anyone ever seen this before and what models had it? Looks like an extra spark plug hole cast into the cylinder heads on a '25 Super X engine that I have. Looks like it was done in the factory, not a home workshop modification.
