    Frank Reed, you wrote:

    "There's also a sextant on the "first day cover" for that first stamp (below), but that sextant has a little curious feature about it. See it?"

    For me, that 'curious feature' is what I perceive to be a gross misplacement of the index mirror--no portion of which lies above the index arm pivot point.

    In the attached image, the white rectangle outlines a portion of what I take to be the index mirror. Parts of the index arm are shown in red.
