It looks like the 306 and 206 but the byte is not as complicated. You will know if you put in a normal needle and it doesn't sew. If it does take the same needles as the 206 and 306 just buy 100 at a time from a
reputable needle place. When you do buy needles in bulk, look the needles over because you have a short return period. Use a magnifying glass and look to see that the shafts and eyes look straight. My sister got some cheap needles - they do not work and there is no return. The needles we got from Av*****h Su*****s from EBAY skip stitches, shred thread, break thread or do not insert into any machine I own because the shafts are not straight. Buyer beware. We will be using them for paper punching I guess. That is a LOT of paper punching. These were suppose to be normal needles.
If that machine has a buggared up bobbin case someone may have tried to use the wrong needle. You will see lots of needle scars. If it does not sew with a normal needle it may need the same needles as the 206/306/319. Those machines are very nice machines and well worth the money. Here is a link to info on them:
