Your machine takes a different needle than most. They're still being made in 2 sizes. Sew-Classic.com carries them.

Looks like your machine takes' "L" type bobbins. Sew-Classic has those too.
I know others have modified their machines to take 15x1 needles that you can buy anywhere. If you search here you should be able to find information on that as well.
Neat machine. It's on my want list, either that or a 320, the free arm version of your machine. I love the typewriter keys for changing stitch patterns.
I "think" it takes Singer flat cams for even more stitch patterns too. I'm hoping someone who owns one of these machines will chime in with correct information.
