Here are some pictures. Some are of me on my 1971 Auto Ski 340 and
one of my father with my l'il sister.  He is on his 1973 spitfire ss 440 trail sled.
This was taken in the early spring of 1974.

Dave my request for parts has been listed in a handfull of sites and
I was wondering if you might consider making a wanted post on your site.
Let me tell you a little about me.
My father was an auto ski dealer from 1970 to 75 and as a young boy I was
7 years old when my father gave me my first sled a 1971 Auto Ski 340,
I'm including a picture.

My father sold 37 Auto ski sleds and I got back 4 - 1973 spitfire ss 440's so
far and I'm working on 3 more 1973 year model's that I just found.
What I'm looking for are parts for my father's
1973 mach 440's that I'm restoring right now.

He went to the factory to buy 2 that he grass draged and I'm half done with
one, the other is all apart.  These are the only Mach's that came Through his
dealership.  As far as I know at this point, I'm the only one with 1973 mach 440's.
 I know paul from united sports that has ed webs 1973 Mach 650 and
my friend Pete in Minnesota with a 1973 mach 650 other than those guys,
I know of no other mach auto ski sleds around.
