She is a real nice machine!! Sorry it took so long but I backed into this thread because when I went to look for it I could not find it.
But now that I am here......It is a badged machine more than likely a National but I will have to go back and look around and see if I can nail it for you. The wooden pitman arm tells me that its pre 1900. After 1900 the popular pitman are was steel but they did have a few left over s make it a few years past then. So at the latest 1905.
The decals are in really nice shape for the age and the cabinet looks like it will clean up wonderfully. I really like the drawer pulls, very ornate for the type of cabinet it has.
You will love sewing on this machine and if I were you I would buy up some needles for it just to have.
