Thomas the Tank Engine Wooden Thomas Series Wooden Percy. Mattel First Generation 2012-2017 Rare Discontinued Item This is Percy from the Mattel wooden Thomas series. It is also compatible with wooden rails such as Brio, and can be run on the rails. This is a rare, discontinued model from around the time when the wooden Thomas production changed to Mattel in 2013! This is a used item that a child has played with, so there are some scratches and stains. It will be sent in simple packaging and will be posted. I may not be able to wrap it in cushioning material. Thank you.
