Thanks all! Mizkaki looked up the serial number for me and it was one of 25,000 "sent" to the factory floor on February 18, 1914. I don't know how fast they would have produced them or if that number was closer to the front or back of that batch of numbers. I've decided to name her "Page" which was my grandmother's maiden name. Unfortunately, my grandmother's treadle wasn't kept by the family - they just didn't know how valuable she would be to me! Thanks again! I'm so tickled!!!
