The Only 1978 Skybird with T-tops?

I have no idea if this is what it looks like it is. It looks like a real Skybird with a Fisher t-top roof. I got a really big picture (2500 pixels wide) so I got a good look. This might be a really rare car, even one-of-a-kind. The Fisher t-tops came out around December of 1977, and the Skybirds were probably built in January, so it seems like there was an overlap. It should have been difficult for anybody to order one during that internval, so it would be interesting to know if this was built as a VIP car.

I am hoping the owner will send for the PHS invoice and see just what he can find out about this car. It's going to need a lot of work, but of course having the only one in the world does ease the sting.
