Here are pictures of the "wrong" walking foot I have. There are no markings, i.e. manufacturer, model number, etc., so I cannot begin to guess what machine it would fit, although I did get it from a Singer dealer. If you think you can use it, or would like to try it, send me a PM and I will send it to you.
