ALL METAL sewing machine WILL DO IT ALL ~ GUARANTEED !!
It was manufactured in appx. 2004 and if you saw it on the showroom floor

I have adjusted this INDUSTRIAL STRENGTH sewing machine to its
maximum efficiency. It also takes standard parts, like needles, bobbins,
light bulbs, motor, belt, hook, electrical wiring, power cord and foot control.
This machine also has the triple zigzag stitch. This is a stitch that is
designed for strength. And you can bring the zigzag closer together
for added strength, which makes this machine perfect for sewing sails.
