Thanks for the comments everyone. I will try sending to Billy. I trid a search for Dressmaker JNZ567528 (that's the number on the underside of the machine) and I get 'no results'. I'm thinking of printing a picture and taking it to the dealer where it was originally purchased.
I have the accessories tin which holds the extra feet and the 24 cams that drop in the top for various stitches but it has nothing on it. The instruction book which has pics of my machine in it has NO name on it anywhere. I may just name her Missy for MYSTERY!
