approximate center of the 1931 glo disk marker<br/>
if you compare the point formed by the middle of the hole in the <br/>
triangle with the point formed albeit implicitly by the tee junction<br/>
you will notice that they do indeed fall several millimeters apart<br/>
<br/>
& tho that was fine & probably even went unnoticed in 1931<br/>
given the present state of survey art in 5 or 6 decimal digits of <br/>
degminsec &or statute feet<br/>
which equates to submillimetric accuracy<br/>
these 2 positions would today be acknowledged & expressed as <br/>
2 different geodetic points</div>
