If it doesn't work it is probably because of bad wiring as stated earlier.
The seller will find the 39 to be difficult to sell because it is limited to vend only small Coke bottles.
There are also many to choose from because of high production numbers, but very few of those are as nice as yours.
The value of the drum and coin mech. alone would bring $500.00. If it was faded or had an old repaint, $500 is average value.
But if this machine cleans up well enough, it's value will almost equal a similar 39 that has been restored.....$2K.
In the condition it sits, I'm quite sure $750.00 will buy buy you your "first" machine.
