It appears to be a wedgehead to me. It also appears that the score reels are at lower center. The only wedgeheads that match that criteria are Rack-A-Ball, Gigi, Olympics, Cover Girl, Flipper Fair, Showboat and Foto Finish.
I think it may be Gigi. Has the white space at bottom of the head art. Side art looks similar to me.
This is assuming it is a wedgehead. The head gets larger from the bottom up but it could be the angle of the photo.
