I just checked the Ismacs' Singer charts and wonder if I copied the number down incorrectly. I have L6672586 and it doesn't go up that high, (only to the 1 million). I'll have to go back to double check, but I'm wondering if I'm just reading the chart incorrectly? It's my parents and my Dad is interested in the model and "birth year." It's in their basement storage area. I took pictures, but it's with my sister's IPOD and they didn't turn out too good. It has the Sphinx on it.
