every border stone is technically a turn stone
even border sectors that appear to be just a series of stones in a
perfectly straight line are actually zigzagging all about
however minutely

actually the ones i have seen show a crosshairs & full circle
except the one at the turn point just east of demdpa

we are talking radii of 6 or 12 miles
so footlong arc segments
if really depicted on the marker tops
would have to look straight

they are truly circular if the treaty says so
but any arch on a border marker in these cases would be

again
if the treaty says they are straight then they are straight
& if circular then circular
it is a great question & worth answering at least once if you can
the best example may be on dzly very near dzlytn
a 20 mile semicircle marked by perhaps 14 stones
per ibs number 1
which could make it distinctly polygonic rather than arcuate
