Alright, I'm new to this, so I will start here. I have come HO scale locomotives and rolling stock. One piece that Ic ame across is an American GK Locomotive Works, E60 CF Burl. Northern, locomotive, stil in the box, from 1976 or so. I would like to find its worth and possibly sell it to a good home. I also have some other locomotives and rolling stock, ( mostly AHM ) from the same era, all new and in their original boxes. Can someone help? Thanks.
