I was looking at that same snowcat, guy said someone was coming to buy it. The yellow Spyder I had was a good cat, the steering is a little hard to get use to at first but fairly simple. The cross pattern is a diamond on top the same as the bottom, the two slots in the middle are for turning on a dime(pull all the way to the left and both tracks will turn in opposite directions turning the cat to the left, same as the right). The diamonds are for forward and reverse, the more you move the joy stick into the diamond(get your minds out of the gutter kids) the faster the cat will go and of corse moving the stick to the left or right in the diamond will turn the cat while moving forward or backward. These cats were built in Calgary Alberta Canada, I was told they were built in the back using Foremost parts, they discontinued the smaller cats and went towards the very large industrial cats. The cat in the picture is a 1971. Parts for these cats are fairly easy to find at places like Princess Auto(large discount store in Canada). I would buy it
