Oh something I forgot to add to my post. The main thing about your machine that makes me think its that late is the fact it is set up like the White sewing machines and Jaguar badged them for White also. And it is set up to run a twin needle, the bobbin winder is like the 1320's and the knob positions are a preview of the 1970's Kenmores.
The needles should be the standard 15x1 so it should not be hard to find at all. and you can still get parts like the bobbins (class 15) an the cases at your local Sears.
