Hello you are purchasing a 1933 mills vest slot machine. I believe all the parts are there, but it may need a few small springs, bolt etc to be 100% complete.
The mechanical parts all appear to be original, the lock and key do not appear to be original and as you can see it's been repainted. I do not see any rust on it. It measures approximately 7 7/8 x 6 7/8x 7 7/8.
Thank you and good luck!
