Mills Bursting Cherry 5c Slot Machine Circa 1930s

It did jam up on me once but wasn't too hard to get working again. Also one area on the bottom left when looking into the inner working of the machine has a lever that is not attached to what it is suppose to be attached to. I had re attached it once and after about fifty pulls it had came unattached again. Not sure what it does since it work before I put it back on as well as Durning and after it fell back off.
