Hi,
The machine in question is NOT a Jumbo Parade, but a Mills Square Bell, without seeing a better picture I would think it has been taken from its original cabinet and installed in another cabinet, in the published picture it shows what looks like a wooden coin entry, when in fact the original had a metal low top housing that held the escalator (See picture of the Mills Square Bell).
I am a big fan of console models especially the electronic models of the 1940's, today hey are very undervalued in my opinion, but many of the features on them are still popular in the games of today.
