I obtained thiss Chessie Tender in an auction lot. I wanted other items in the lot but as with all "lot" sales you get everything in the lot. When I picked it up it sounded as if there was a bunch of loose parts or gravel inside. I was sorting through this last night and almost pitched this tender in the junk pile to be discarded.
I took the cover off this morning and found that there are no motors, speakers or electrical parts in the tender. Just a wheel the turns as the car goes down the track. This wheel has something inside it that makes the noise. The part number for the shell is 1130-27.
I am attaching some photos. I think that this tender is working as designed and that the noise is supposed to mimick some sort of train sound but I am not sure as I have not encountered this before. (Yes I am rather new at all of this).
If anyone knows the Lionel number or any information that I can use to get to know this tender I would appreciate it.
Thanks!
