Hey Caroline,
Thanks for the info. I couldn't find a plate with a model number. I saw that was where the model number is on a lot of the machines I looked at online but no dice on this one. I took pictures of all the plates and numbers I could find on the machine and captioned them on my blog - except the two stickers from the Missouri Sewing Machine Company, who apparently serviced the machine some time after 1997 (the date on one of the stickers).
