wolfgang & or anyone else who is trying to get this

let me try to be clearer because i believe there has
been a breakthru now

please compare the 2 tricolor tripoints you have
selected due west & due east of coburg here
http://www.ieg-maps.uni-mainz.de/gif/71th_a4.htm
with the same locations on any modern map of the
bavaria thuringia state line
such as hopefully this one if it works or better
http://encarta.msn.com/encnet/features/MapCenter/Map.aspx?TextLatitude=39.45&TextLongitude=-98.907&TextAltitude=0&TextSelectedEntity=39070&SearchEnc=false&MapStyle=Comprehensive&MapSize=Small&MapStyleSelectedIndex=0&searchTextMap=germany&MapStylesList=Comprehensive&ZoomOnMapClickCheck=on

but of course preferably use as fine a map as possible
& certainly with modern subdivisional entities & their
borders included if possible
since they could give just the final clues that are
needed to identify this as a living tripoint
if it still is one

now the bavaria thuringia border may not be entirely
the same as the coburg meinengen border
but these 2 bavaria coburg meinengen tripoints & their
vicinities dont look any different on both those
borders actually from 1848 to 2005
so far as i have been able to discern
& so
all else being equal
i agree
go either east or west from coburg

but in fact according to this 1812 map
http://www.ieg-maps.uni-mainz.de/gif/p812d_a3_mb.gif
only the tripoint to the east of coburg is looking
very likely to have been any kind of a bavaria
tripoint as early as 1806

this location btw appears to be at or very near a
place called plesten
with byth again hopefully indicated as a dashed line
here
http://multimap.com/map/browse.cgi?client=public&X=1243750&Y=6460000&width=700&height=400&gride=&gridn=&srec=0&coordsys=mercator&db=DE&addr1=&addr2=&addr3=&pc=&advanced=&local=&localinfosel=&kw=&inmap=&table=&ovtype=&zm=0&in.x=6&in.y=6&scale=50000
all too crudely of course
but thats the rough idea anyway

& this may well be virtually qed on jespers pic
if its caption is not mistaken
but happily the rock or rocks still remain to be found

& especially if you are looking to save gas
i would scour byth first just northeast of plesten

& thanx to all for trying in any case too
