It's hard to tell with only one photo, but it looks like a Jennings slot with a Pace jackpot conversion front. Additional photos would help to identify it. Most of the repair books out there (such as by Mead and Geddes, including for the Jennings machines) focus on later (mid 1930's - on) versions, but would still help you with a 1920's or early 1930's machine, for repair and restoration.
