Hello, I do not know much about the different brands of model trains.  My father left me with several hundred various types and I've been working to sell them on ebay.  For those I had in the original packaging that hasn't been an issue but the left overs that are loose do not show any distinguishing stamps that I can find.  All of what I have unpacked so far have been packed and in storage since the mid 70's.  I found newspapers in the box older than me.  Most are plastic, some are metal or wooden bases with metal housing.  Does anyone here know how to look at an engine or car and be able to tell who the manufacturer is?
