That looks like the one. The eraser carrier inverts as with other Sheaffer pencils of this general style to neaten things up when the eraser is not needed.Daniel,
Is the exposed-eraser pencil in the upper right of this ad a Utility (I or II?) pencil? And a Utility II to match the Socereign/Admiral/Craftsman would thus have gold trim instead of chrome? And they came in stripes, not just black? Oh, do I need one of each!

As to the Diana II pencil, I've yet to even see a Diana, Minerva, or Milady, let alone their shorter pencils.
