Here is a set of spare parts for one of my Union Pacific's Water Tender Pre-Rebuilt (1955-2007) kits.
It includes all 4 ladders and a tool box.
They will require cleaning before painting. I recommend washing with warm soapy water then soaking in 'Goo Gone' or similar product for about 24 hours. Then rinsing off with warm water and allowing to dry.
