Picked up a 8801 Blue Comet from the late 70's early 80's that has nary a chip on her, looks like it was pretty much stored most of her life so to get her running strong again I had to get the old lubricants out that had turned to a thick gunk then re-lubricate her. Runs like a top but with that hokey sounds of steam chuffing sound. My question is, does it have a whistle that is supposed to be on that sound board too? If so it ain't working and if it is supposed to have it, is there a replacement for that board out there that is either NOS or aftermarket? And the other question: if it does not have a whistle, would I ruin the value down the line by putting an aftermarket board in it that has the sound of steam WITH a whistle if I am able to find one?
