Willams part no 16-9471

[newdos]

Whilst shopping my BSD found this in the bottom of the cab as was about to bin it as I thought it was from something else until I noticed the part no looked like a williams part no and sure enough it is listed as a BSD part - never seen one of these before a sticker for the theme music - anyone else? guess it its becase it needed permission to use it. where did they normally stick these???
