Hi,
my experiences with sewing: I have made or adapted couple of battledreses and made for my Austin K30 new seats.
My sewing machine is usualy old electrical Czech Lada, stronger will be better.
The mains problem is with the threads. You will need any stronger but not thick. And the second is the needles. I am using needles for jeens.

But the first step is, if you have, take the original one piece and look how it is sewing together!!! When you can rip it for better knowleges of old work.
