Just a quickie, and I think I already know the answer but just wanted definite confirmation please
I've seen a 6630B on Ebay UK but I think the module, or possibly just the faceplate, (or both I guess), are from a 6600? It says "Illuminator" rather than "Fox Fire", and there's no silver surround either.
The backplate is Japan M, so also pointing towards a 6630B.
So I guess I've answered my own query, but can someone confirm what I'm thinking?
