I was thinking sample or maybe one used on those little kiddie trains like the one Steve Martin was engineering in the movie "The Jerk". Any salesmen's sample i've ever seen was a true and accurate representation of the full size version, which this is, except for the color. I've never seen a chrome or polished steel coupler. That being said, it could still be, and probably is a sample piece. The first thing that needs to be done is to id the actual type of coupler that it is. It looks like a Janney coupler, though I don't know what type. Exciting piece regardless. Interested to find out the rest of the story, whatever that may be.
