Hello all, I have come across this engine while cleaning out the Mother In Law's garage. Its a Crescent Limited and from what I can gather it is an HO scale. The last time I looked for it online I came across it being sold around $300-$400jawdrop, and from what my wife remembers is that the MIL paid about that much for it. This thing has never been out of the box, has a certificate of authenticity numbered 899 out of who knows how many. Its maid by Mantua Industries Inc and from what I can find out about them is they closed down in 2001. I have no interest i n this other than to sell it really and would like to know if I have something thats truly worth something or not. ANY info would be greatly appreciated. Im attaching 2 pictures if they turned out. I placed a 3.5" floppy disc next to one of the pictures to give an idea of its size. I cant upload the pics they are too big so here is a link to a blog I work on from time to time. http://jacksremodeling.blogspot.com/ Thanks again.
