With the button part being movable it looks like a cuff link. But then again it may be for the lapel button hole.
do you think it is original? if you from what you can see?
I would like to see close-ups and clear.
So far it is very interesting.
original membership diamond which has had a lapel attachment fitted by someone (probably when then pin came off)
thanks of the answers but I'd like you two last questions ...... if it is original, inche year may have been produced? and how this may be worth?
