Catwalks on Santa Fe Texas

I have a MTH 20-3056-1 Santa Fe 2-10-4 Texas Steam Engine. I purchased this at an auction. Runs great but when I opened the box one catwalk was loose in the box. The others have come off as they were not on very well. Two are missing. Does anyone know where to get these parts or Someone who can make them and install them. They are brass painted black. The engine is flawless other than the two missing catwalks and the others falling off. Email is in my profile or respond here.

Thank You
