The image put up by creskol is pretty much bang on to what you have . Is it certain that what you have is a cufflink , not a button ? I'm not sure it's an important distinction - but i raise the question since the image creskol put up was in the context of buttons .
Thanks, it really hasn't sunk in good yet though .... man I cant believe it. You just NEVER know what going to come out of the ground.
