Thanks for the replies. I took delivery yesterday. It's a "N" date code, and she is in great condition. The dust on the lid, in the photo, made it look like it was painted white. All I have to do is apply a little grease, and she'll be as good as new.
My Grandson saw it, and excitedly proclaimed, "Look grandpa, a teeny tiny cooker!!" He then claimed it as his, and well, we all know that I am no longer the owner of a 1991 SJS!
