Two additional views of the possibly misidentified and misnomered 'cantilever tip' item. These two were processed in the AFM CFM software know as SPIP which can be downloaded as a trial or evaluation full functioning software package. Image Metrology makes the software available with the presentation on equipment sales. It seems to work very well, but this is only cursory simple images I produced using it.
Two views of the altered item I am offering as a possible match for the current item at reply #244 & 245.

Unless someone has a comment I'll work on something else. I can see the related content, but as with the MER imaging, we all like be careful about jumping to conclusions, and we don't even have acknowledgment from NASA about these items to my knowledge.
