I have an  N-scale Con-cor Hudson made in Japan. In the process of repairing a wire, I lost one of the motor-brush springs. Finding a needle in a haystack has nothing on finding this spring. Con-cor is a wash-out for parts, so I was wondering if anyone has any locos for sale as parts or motors or the pieces I need. I have heard some of these locos were notorious for not working very well, this one pulls very nice, and as it belonged to my late mother, I very much would like to get it up and running.
