I don't know anything about the machines. Wish I did, but I just wanted to say, that you have found treasure. I would love to have the Seiko. It looks like the one Donna Jordan sews on, but I think hers is a different brand.
Edited to add: Donna sews on a 20 year old Consew at a rate of 6,000 stitches per minute. I have to laugh, because if I tried to sew that fast, there would be no straight seams. lol Jack & I are already good friends, and we would become better ones.
