the attached brcove try you made 15 months ago is all dead links 
now 
so i dont know if the following pix are improvements 
or just replacements
http://www.postalven.com/pedro_milano.htm
http://tinyurl.com/iua2 
& strangely enough they could be either class e
or class d
or c
or even b
for i have ascertained from ibs numbers 174 & 175 that the 
tripoint falls on the thalweg of the rio negro 
opposite the distinctive piedra del cocuy in the pix
so these could have actually been shot from the tripoint itself 
for all i can tell
or perhaps from your san jose island
which is said by the same source to be just nw of the tripoint
& from the same source i learned
there is not just 1 but 2 brve monuments on the left bank 
tho they are evidently not large enough to be visible in the pix
& there is at least 1 brco monument on the right bank too
also this trijunction both as described & as shown here
http://www.info.lncc.br/wrmkkk/ve1.html
is evidently a rare triple intersection 
of a thalweg with 2 geodetics
indeed i cant imagine how they got them all to coincide in the 
first place
nor how they can keep them from coming unstuck as the 
thalweg wiggles around
