I do wonder about the disappearance of the picture.
The mortar looked interesting and fairly "correct" and it would be nice to know more about it.
(As a sidenote, when a picture is posted on the forum, if the picture is later moved or changed on the photo site that was linked to the post, it will cause the picture in the message to vanish.
Folks: When you post a picture on the forum, please do not move it to some other album or folder at the Photo Web Site (like Flicker or Photobucket).
