How do I sew this back part of a moccasin?

[MrLentz]

Hello,

I am re-making a new pair of these moccasins for myself out of real shearling. Upon inspecting the machine stitching on the back (the curved stitches noted by the arrows), I was wondering if anyone knew how you would stitch this part on a machine? It seems awkward to try and fit it on a cylinder arm sewing machine, but maybe it is forced into place? Or would they use a patch machine where you can rotate the feet to sew in any direction?

 

Thanks!

It would be most likely to your benefit to sew the heel tab by hand. I remember seeing these made in New Zealand, (early seventies) where I worked but only remember the heel tabs were sewn on a dedicated machine. I hand sew all my mocs.
