I just saw that this guy also has two versions, FS9 and FSX, of the Golden Age Sims New Standard D25 on Simviation. This is a payware plane. It's the whole plane, apparently modified with the Shockwave lights, and a repaint.
I just sent an e-mail with a heads up to the guys at Golden Age Sims.
I hope SimV will be more helpful to them that they were to me when I once asked them to delete a file that had been uploaded there in violation of the restrictions in the ReadMe, and they were really snotty about it.
