There were a couple people making porcelain signs in the 80s and 90s and to me, these feel like a "piquadio special" but I could be wrong.? I have come across some weird ones around here because of that person and a couple others, like another I heard of up in BC. This is one of the more obvious ones (and not porcelain) but there are others, that I've seen and touched, that are not as easy to pick out, and Many fake lenses from those folks too.
The best way I know to confirm originality of a sign is to find a old pic of one in use and I've seen a lot of Flying A station original pics and not one with a black wing, but, again, I could be wrong. Getting your hands on a original dealer advertising catalog is another sure way to know.
