Antique Mills Slot Machine 5 Cent Special Award 7-7-7

Antique mills 5 cent slot machine. This is a Antique slot machine mechanical type, it appears to be updated with lights at some point so it does have a electric cord to operate the lights only the mechanical is still the original. I have had this for several years just sitting.

I tried putting a coin in it, but it wouldn't work it didn't release the lever so l released a couple coins in the unit it seems to at that point spin the wheels.
