Hopefully, somebody has an answer. It looks like a reproduction decal. I have seen reproduction Beaumont 396 ones, but never a 427 one. Possibly Bruce Levy @ blaap.com. He has the 396 ones, so it wouldn't hurt to contact him and ask.

That decal shown is on my engine. I bought it years ago from a member here that had sheets of decals custom made. I don't remember which member it was.
Edit. I found the original listing for these decals.
