I have an affinity for vintage sewing machines. They are such work horses and I know how to clean and repair them myself without having to pay big technician bills.
I found this 328K …the K means the machine was built in Great Britain. It is what is called a 3/4 size machine like the steel Singer 99 but the 328 is a lightweight aluminum machine like the Featherweight. It will do a zig zag and decorative stitches with the cams that load in the top.
I thought it was a great deal at $23 !

OMG $23! Awesome deal! I love the old machines, too. Love tinkering with them AND sewing with them.
What a great find! Love the colour of the machine – very retro.
I just said the exact same thing about keeping machines repaired in my blog. I'm enjoying your artwork and blog while trying to beat the heat. The "Purification" is marvelous and thought provoking. Greetings from Tunisia!best, nadia
