Nick,
John Gillard explained to me that the basic Six radiator grille is exactly the same pressing as that of a Big 15 or Normale. The only differences are the bracket welded top center for fixing to the top of the rad and the additional holes plus two captured nuts at the bottom to take the air deflector plate. I was not prepares to try and salvaging my original grille which housed the only rust on the vehicle – so I obtained a very good Normale grille and had the changes made before chroming and painting.
So I suggest you widen your search to include Normale grilles.
Otherwise, I do still have my original 6 grille. Rust has penetrtated in a couple of places but I could send pictures if you think it might be better than what you currently have.

p.s. – Re your 11CV gaskets – I believe you have quoted an incorrect part number ….
The Payen ref, CS1A152, applies to a “conversion set” – that is the set for the bottom end of an engine which, together with the relevant headset, (HS1A152) creates a Full engine set (also sold in pairs as FS1A152).
CS1A152 should only contain the sump gasket components consisting of the two long side pieces and the two semi-circular crankshaft seals. Definitely no head gasket.
The Payen reference for the head gasket alone is 1A152.
Cheers,
