Nice vid. I wonder what machine that is?

A Brother B75 I believe from watching one of his others.
I get jealous of the handsfree foot drop mechanism one these machines!

I had a, singer 20U, great machine industrial.
you need the space! A jack of all trades.
It is an artisan 'versatile' machine. Unlike most industrial machines where the are designed to do one so a like high speed 60# 70's wig_zag home Sewing machine.

Able to do just a few or single stitches for precision.
