Moving my Montenegrin collection, and found one I can't place.
Looking for any information people have on the stamp on the right, from Montenegro. It's an overprint of the one on the left (Scott #82).
A friend who knows Cyrillic (but not Serbian too well) has said the overprint references something like "trademark/legal registration", and there is the date of 16/VI 1909, so June 16, 1909. So perhaps #82 was overprinted for fiscal use by the government? Potentially the whole series it belongs too?
Thanks, Greg
