Two of the three pressed-metal vintage Marx locomotive shells I've earmarked for specific renewal and rebuilding of other Marx toy-train sets and items already in my collections. The other shell is a "parts-donor" piece that will help with repairs and renovations in the future. Besides, I obtained another vintage Marx wind-up locomotive to add to my toy train fleet. The price was right for these useful items, and I'm fully satisfied with this eBay transaction.
