I love this! I've begun a little train motiff collection for my youngest boy. He is CRAZY about trains.
I am not sure how it got to be that color, I found it in an antique store, for a quarter. There are some tokens that were solid red and blue, not sure if they made a rainbow.
Best bet is to start a new thread. Things get hurried here quickly. These types of pieces can be difficult to assign a value too.
