This appears to be some kind of an operator revamp, that someone has plugged the original coin entry position
above the sunburst, and relocated a standard gooseneck mechanism, by putting a new hole on the right side,
which makes the escalator feature useless. Makes one wonder what is going through some peoples heads! But
realize, this was most likely done many years ago, when people used whatever was available, to put a machine
back on location. I can't tell what denomination the coin entry is, in the pix, although the inside sticker says 5c.
Below is a pix of what a "Century Vender" gooseneck model, with witness window, is supposed to look like.
Also notice that the coin entry is located much higher.
