Scored this really nice green base 520 searchlight car. I was momentarily dismayed when it didn’t light up but screwing in the bulbs took care of that. Probably the easiest fix in toy train history! Pretty happy with this find. I think now I do have every color scheme of 500 freights. Not every variation, but the base colors. Gonna double check my Greenberg guide on that now.
