Audrey is five now, as of today, and here she is with the shiny little Singer Spartan sewing machine I gave her. She loves to sew, and a Spartan, with its motor removed and a handcrank fitted on, makes the best sewing machine ever for a young child. Please do NOT buy any child a plastic (or metal, for that matter) "child's" sewing machine. Nothing will discourage them more. Find a Singer Spartan and go to TreadleOn and learn how to replace the motor with a handcrank mechanism. It's easy or, believe me, I couldn't do it!! Once you have the spoked handwheel and the crank, all it takes is a screwdriver and about five minutes of your time.
Audrey's machine was made in Kilbowie, Scotland in 1960. I found that out online. Of course, the K in its model number already told me it was made in Kilbowie. That's what the K stands for. Its serial number is what allowed me to find out when its batch was ordered.
