When looking through that many insulators, you find a few oddballs. There were a few with upside-down markings, and a couple new marking varieties. The range of glaze colors is very interesting as well. This M-3725 looks like it was made of spongeware, and is covered with pimples! Too bad it was broken so badly... but there were actually three like this, so at least one should be reconstruct-able. Next: [id=80682318]
