Whats my name? Mills Jackpot part

[MiMark]

So i've acquired a nice War Eagle machine. But from me reading here in CoinOp, the jackpot mech has been messed with I think. From what I can tell there are some parts missing. Can someone tell me how to acquire these parts; what are their names, part numbers, and a source?
See the attached photos of my messed up mech and what I think I need.
Thanks a bunch.
