This is a pair of replacement pilots or cow catchers for an N Scale Con-Cor Galloping Goose.
This model has been designed for FUD & FXD materials. If printed in the FUD & FXD materials it will require cleaning before painting. I recommend washing with warm soapy water then soaking in 'Goo Gone' or a similar non-corrosive product for 24 hours. Then rinsing off with warm water and allowing to dry.
