    Hi Kevin, Thanks for following up on this. I am not at home now so can't check for holes, but will do next time I am home. The only extra hole I saw is down were I removed the gong to get a better picture of the label. There was one extra hole in that area. David

    Seth Thomas Gallery with a broken hinge

    Without having it in my hands I can't tell from the pics how it was originally secured to the bezel. I don't see any sign of solder on the mating side of the bezel which is concerning.
