I am confused by ads, even from big retailers, that are selling used locomotives. Often, they state that the loco is rated C-7 in Excellent condition. But then, many of them say sold AS-IS, without saying that they were ever tested. And, sometimes, after stating that they are Excellent, they disclose that the bell, whistle, or forward/reverse doesn't work (I.e., "runs in forward only").
How can any loco that isn't fully operational for any reason be called Excellent??? If this is permissible, then the term "Excellent" really has no meaning.
Thanks for all info.
