Gilbert made the 24558 Canadian Pacific flatcar with Christmas style trees as the load. They were made in 1959 and 1960. The flat car has a rarity of "2", which means they are not hard to find. The tree load has a rarity of "4", which means good luck finding any. Over the years the trees were lost, tossed or disintegrated. The going price for a complete car with load is $400 to $450. Just the flat car is about $40.
