You have a 99, one of 15,000 commissioned April 10, 1928. It is a 3/4 version of the 66.
I have a 66 built the same year. My Grandfather bought it for my Grandmother the year my Mom was born. It originally lived in a number 40 cabinet, but my Mom has the cabinet with her 401 in it. The 66 was but in a case then and probably has not been used since. It turned up in my cousin's garage a few months ago, and is quite stuck.
Did you get the manual and attachments? the picture looks like it has a cording foot on it. It will use class 66 bobbins and low shank attachments. You can get a new slide plate if it wasn't with the machine. Your decals look real good! Most have them worn off in the bed area. To start off, you can wipe down the outside with sewing machine oil (oil her good inside too). I think there is is some good information posted here on the board for further restoration.
Enjoy!
