I looked at the pics of the inside and it didn't look right to me, although I hasten to add that I DID NOT see it in person!
For me, the casting look repro or they have been blasted.
The base plate looked old and rusty, but the castings (from the inside) and the jackpot looked much cleaner than the rest.
Also, back door was not correct and no Mills snake key.
Sorry if I have ruined anyone's purchase.
I'll get me coat.
