meaning two different tripoints&#39; positions.  <br/>

<blockquote><span title="ireply"> &gt; &gt; &gt; the marker is unusual in indicating 2 distinctly<br/>
&gt; &gt; &gt; different tripoint <br/>
&gt; &gt; &gt; positions a few millimeters apart<br/>
&gt; &gt; &gt; tho both are coverable with a single touch of an<br/>
&gt; &gt; &gt; index finger<br/>
&gt; <br/>
&gt; focusing closely on the 2 different die stamps that<br/>
&gt; appear in the <br/>
&gt; approximate center of the 1931 glo disk marker<br/>
&gt; if you compare the point formed by the middle of the<br/>
&gt; hole in the <br/>
&gt; triangle with the point formed albeit implicitly by<br/>
&gt; the tee junction<br/>
&gt; you will notice that they do indeed fall several<br/>
&gt; millimeters apart<br/>
&gt; <br/>
&gt; & tho that was fine & probably even went unnoticed<br/>
&gt; in 1931<br/>
&gt; given the present state of survey art in 5 or 6<br/>
&gt; decimal digits of <br/>
&gt; degminsec &or statute feet<br/>
&gt; which equates to submillimetric accuracy<br/>
&gt; these 2 positions would today be acknowledged &<br/>
&gt; expressed as <br/>
&gt; 2 different geodetic points<br/>
&gt; <br/>
