This slot machine backdoor looks to be original and was told it could fit a Caille machine.It is very well made and it weighs 11 pounds and is made out of 1/8" steel and it has a simulated wood finish.I'm not sure what machine it would fit but the overall size is 18 3/4" W X 14 1/4" LÂ not counting the mounting bracket at the bottom and inside measurements are 13 15/16" X 18 5/8" but the cabinet size of the machine should be an 1/8" smaller on each measurement to make sure it would fit .It comes with a replacement lock. There will be no returns on the item.
