This is in for a full overhaul. Completely jammed and won't move.
Update: Performed a complete overhaul by disassembling the entire machine to soak overnight in a solvent tank. Hand-cleaned every part during assembly. Oiled and greased per manufacturer recommendation. Had to fabricate the dual spring hanger since the original was broken. Had to fabricate the safety slide since it was missing to avoid coin jamming on payouts. Tested and pays out as it should. Came in without bonnet, backdoor, and cash box.
