I just purchased the antique table clock at a thrift store in my town. It has an E.N. Welch movement. The gong looks like it was replaced with a bell. Everything is intact and the clock works great and keeps proper time. It does need a good cleaning as it looks like it was over oiled. Th scroll work decal on the back side of the glass is peeling back in a few places. Any help with this would be great.
