I wrote to PPG about the decals with serial numbers that are afixed to Joe's (Project 727) 727 simulator.
They said they would be happy to supply my 727 with authentic PPG decals for the glass panels. I was shocked to say the least. A major aerospace corporation helping a sim builder???
I sent a series of photos to them and should hear something back by the end of the week.
