I was interested in this machine, too… You beat me to it, but saved me 6hrs on the road
This machine should have had a payout mechanism, in addition to the ticker tape. It would have been battery powered originally, using 6v dry cells.
IPDB has a neat ad showing the three playfield options: https://www.ipdb.org/showpic.pl?id=4314&picno=40686
Good luck with your restoration, neat machine!
