This one came with a walking foot. I'm currently making a canvas top for my 1961 Willys that my Dad bought new in 1961.
Best suggestion I can make is to try it on some samples before investing in the full leather for your seat.
That's how I found out my 50 year old White machine would sew marine canvas - with tweaking of the bobbin tension.
You'll need the right needle and thread, of course.
