Hi, I have a National (De Luxe Rotary) SN: B250393 that doesn't have a needle clamp. The one that came with it was made by some one. See photo. Next picture is of the needle bar without the clamp. Could some one post a picture of the correct needle clamp? I don't know what to look for in a replacement. Thanks everyone for all your help. I love tinkering with the old machines, almost as much fun as quilting!
