Thanks for the info! I ordered bobbins from them and they arrived today. Next problem is: The gentleman who sold me the machine provided 3 metal bobbins. They don't drop in. They stop about 1/2 way. All 3 of them. I spin them, turn them over and I cannot get them in. The new bobbins are the same size and they don't go in either. I feel like the bobbin case is either out of round (doubtful) or has been swapped out with the wrong one? The machine had a pre-wound bobbin in when I bought it. Thoughts? WAWAK doesn't carry bobbin cases for the 153.
