Vintage Sewing Machines (NE Fort Bend & Alief)

I am looking for a Singer 192/Spartan (whether it works or not) so I can get a couple of parts to use to fix my sewing machine. A Singer 99 has some parts that will also work. Both are basic black painted metal machines - the 192 has the word "Spartan" in gold on the top & the 99 has gold decals and the word Singer in gold across the top of the machine (needle on the left).
