Original Wells Gardner K7000 series arcade game monitor chassis. We aren't 100% certain which model chassis and tube size this one is. It does have a part number of 85X0216-011E / P447 stamped on main board and 85X0221A / P456 on the neck board.
Chassis is missing Q11 from what we can see. It is dirty, untested and sold as-is, probably safe to assume it will need to be rebuilt and / or repaired.
Please note: working with monitors involves high voltages and can be dangerous. If you are not familiar with monitors we do not recommend installing an item like this.
