I forgot to add that more than likely the machine will take a needle system 20x1. There are sometimes that system of needles that are available on ebay. Some will just drop the modern needles now known as
130/705 H a little bit. There is a thread called
15x1 rather than 20x1 needles
on another forum that uses a magnet the size of the difference to make sure the needle is in the proper position.
