Original, untested Wells Gardner K4900 series arcade game 19" CGA (standard resolution) monitor chassis. This chassis does have a broken corner on the main board, probably can be repaired, but some traces will have to be jumpered. It is untested, we found it in a box of spare parts from a warehouse cleanout, consider it for repair or parts. Sold as-is.
We believe this is the "early version" of K4900 chassis (we don't know the exact model number, but it does not have a vertical dampening pot). The part number on the main board is "2061433-023".
Please note: working with monitors involves high voltages and can be dangerous. If you are not familar with monitors we do not recommend installing an item like this.
