From my experience most needles interchange but I know some of the rare machines take a special needle but they are available.
The quilt forum Vintage group could tell you more but if a needle is in them you can compare to the Singer .
Think people are busy in their gardens so haven't had time to write to you yet.
Or else they are like me and envious because you have access to these machines !! Ha ha . I have enough but would still like a Singer 301 only because the group says such good things about it.
