This model seems to be pretty hard to find. It will need some work as seen in the pictures. I can only point out the obvious stuff as I'm not an expert with these machines. It is missing the lower front glass. It is also missing the lock on the back cover.
Back cover and back upper are completely detached missing the screws. The machine doesn't operate when pulling the handle. I do here pressure in the lower cylinder when pulling the handle. I'm not sure what it will need. Will need a cash box.You're welcome to stop by and look at it if you're in the southern California area. I will have to sell the machine AS IS.
