I'm sorry to hear that your machine got so damaged in shipping. Packing a machine for shipping is not a job for the faint-hearted - it's a lot of work to do it right.
You might try joining the treadleon mailing list if you could post some pictures of your machine on picturetrail or webshots or something, someone with a similar machine might be able to provide a manual or replacement parts?
Or, if yours is well and truly dead, maybe someone with the same machine is looking for replacement parts that you might provide? :)
