McDD MD-82: USAir (post Piedmont/PSA merger)
Welsh + ATP decals

I know that Allegheny flew DC-9-51s, but after it re-branded as "US Air," it merged in the PSA fleet of MD-80s, which then received the Allegheny burgundy scheme with USAir titles. I will splice two ATP US Air burgundy decals together to make it work. This was a very short-lived livery from 1988-1989.
