Vintage Harold Beveridge Model 2 Two 2SW-1 Electrostatic Panel Parts Repair

This listing is for a single Harold Beveridge 2SW-1 electrostatic panel. This is the middle panel from one speaker. It overall looks to be in excellent condition.

There are some light spots on the aluminized coating. Nothing that looks like delamintation or loss. They look like small water spots.

Though I do not believe water caused them. There are a few bits of diffuser foam between the slats. I did not try to remove that. I was not able to test the panel, since the amplifiers are non functional. I have three more panels I can make available.

The panel measures approximately 13 3/8 wide by 23 3/8 tall by 7/8 inches thick.
