Hello,
I just joined this site this morning. I was thrilled to find out you have the same machine that I purchased today at an Estate sale. I hope you are still following this and the message gets to you. I had a few questions and you seem to really be enjoying your machine. I would like to find out if you know where I can get a manual for this. I know you got yours with the machine but do you have any ideas? I am a complete novice although I did learn to sew at 9 years old on a treadle model and I am surprised that some of it is coming back, especially after 50 years! Also, where do you find the serial or model number on yours? I can not locate it any where but I do know it is a National Vindex B Sphinx. I thought they were all engraved or stamped in but I can find nothing. I am so excited to start using it but I really want to be prepared for all the questions I know I will have. Any information would be greatly appreciated.
