I know this cat and reached out to him when I saw it with a for sale sign in one of the Vintage show pics.
Tom who owns this did a great job restoring it. It's right up the road in Kingston NH. I asked him to forward me some better pics and a detailed write up to post on here. I believe the reason it is up for sale is that he runs it on Lake Winni Alton area and haven't had the ice in a few years and cats don't swim well.
Prior to him it's life was a purpleish 442 snowmobile club groomer I think from Bow, NH. They brought it to him for repair and then they decided to cut their losses and Tom bought it.
Full restore with cab extension and I think the cab was also widened. Anyways great cat if and when he forwards me more info I will post it up.
Tom is in the metal fab business and also builds movie props. You may recognize some of his vehicles and props in movies:
