In the post Mysterious TT stone blocks rear passage I asked readers whether they spotted anything unusual in the time lapse. Eventually Mr. Invader from England spotted it, another TT stone standing in plain site. Congratulations Mr. Invader!
The “TT” was partially covered in soil and roots but the top part of it caught my eye. It’s the same width and the height only differs by 1/2″. Still no idea where they came from. Be nice to find a third, but I doubt it. Will have to find a good use for them eventually.
