Wooden Thomas Series Merrick and Rock Crusher I believe this is a very rare set. This is a memorable set that I purchased at a UK auction for my child, who loved the mine railway friends in the Thomas series. This set includes a large mine railway track with illustrations unique to this set, and a long downhill track that is not usually included in standard sets. Merrick should also be exclusive to this set, making it quite rare. In addition, I would like to pass this on to someone who, like my family, loves the mine railway friends. I will also include six other engines: Duke, Skarloey, Duncan, Peter Sam, Rheneas, and Sir Handel. The original tracks were too old (the tracks unique to this set are sun-faded), so I will include newer tracks I have on hand. I recommend this to those who don't mind the color variations. Additional tracks are available. Please feel free to comment. ^_^
