I was intent on backdating my Baldwin 4-4-0 locomotive's tender to use the older arch bar trucks that came in the box along with the more modern trucks already installed.  It looked like a simple job – take out a little screw holding the truck in place, swap out the new truck (making sure the contacts are in their proper places) and put the screws back.  To my surprise, little things started rattling around inside the tender body and the mounting screw threads would not hold on to anything.

Does anybody know the way to do this without ruining the model?

Any help would be greatly appreciated!

I recently bought a Bachmann 0-6-0 undecorated settle tank switch engine.  The paint color is exactly the one I am trying to duplicate (so far without much luck).  In comparing it to real live full scale locomotives, it is ideal for a well cared for steam locomotive.  I hope somebody can tell me what this paint color is, how to mix it, where I can get my hands on some of it, etc., etc.

Thanks very much for your help.
