like posted above, there are too many variables when it comes to restoration. I have noticed the term "restoration" thrown around recklessly when it comes to toy trains (and cars too..., LOL.) . To do that "BING" right, it would cost more than 20 of those trains. You cant expect a legit restoration shop to work for free. No restoration shop is a full service facility. They usually have to farm things out. The first thing that comes to mind on the OP's train set is fixing all that horrible pitting which is very hard to do and sometimes not salvageable. Then paint matching, then finding a place to reproduce the lithograph or dry transfer detail work (not sure what process BING used back then). the artwork alone that would have to be made would cost $$, the transfer itself would not be much. Very tedious. We have not even gotten into if new parts have to be made and replating of original parts and lets not forget if you have to find used original stuff to replace things as well. In the end you have to ask yourself not how much $$$$ you want to spend (you only live once) but how much is your sanity worth. LOL. In my opinion, that is what makes a restoration.
Good Luck to all on your projects.
