TrackMaster Knapford Station Celebration Set???

Thanks for letting me know. Does anyone have one of these sets NIB? And also just a side question out of context, my first ever TOMY / TrackMaster item was the Tomica World Talk n Action Percy. I would love to have one of those again, since when i had mine as a kid the coupling between Percy and the mail coach broke from excessive play, so I had to throw it away, but then I always had the green tracks leftover. Do you know where I can find a Talk n Action Tomica World Percy Nib?
