This machine was destined to be mine, I am picking it up this afternoon, a couple of condensers had blown in the foot pedal so Sam has fixed it FOC.
I have been searching for days for a Sigzag sewing plate insert and just a few minutes ago I found one on this very useful site
http://www.helenhowes-sewingmachines.co.uk/index.html The complete Sewing plate with both plates and screws just a tenner, as I have said all the way along this machine is destined for me so I am going to call it "Lucky Me"
