That's a replacement backglass of some kind, I think. It's laid out exactly as Victory Derby / Victory Special, but with a few tweaks (the winner sections in the upper left).
The playfield is likely modified as well - the bumpers are not factory for Victory Derby/Victory Special.
The only Photo Finish (well, documented) was made by Universal. So this further supports the idea that the backglass was scraped and game modified.
I'm not sure what the cabinet is, but Bally Entry uses a different style of cabinet - the center portion is deeper on Bally Entry. This is the same depth as Victory Derby/Victory special, but it's missing the hole for the shuffle reset. On those cabs, there is a giant push bar on the front that manually actuates the shuffle rather than use a motor like on other games. --Edit-- looks like the hole has been filled in. Look for the big circle to the left of the shooter rod.
Bally Entry's light board is also wildly different than Victory Derby/Special, so the lights would be flashing all over the background if they just swapped the glass.
These are all just guesses, but those are my thoughts.
