I have the box for a HO SOO LINE 42' Steel Gondola, but not the plastic INSERT that fits into the box. This is in the OLDER PRE-SILVER SERIES type of Box for HO Gondolas. I scrapped the INSERT a few years ago because it got damaged. The box and the freight car are both in good condition. I would like to know if you have the Box Inserts that fit into the boxes of your HO freight cars. David Briel.
