This is a fine locality thumbnail pyro specimen! It was in the collection in a box with the larger piece above, but seems to be a separate specimen obtained at the time, and not a trim per se. As above, I cleaned them with water only and not chemical or physical abrasion to remove the old pocket dirt, because I thought it interesting.
