Backmarks "Extra Gilt....."

"Extra Gilt..." backmarks were generic stock backmarks or tradename backmarks denoting quality.  There may be variations of this backmark, uncertainty as to who the actual producers were of some of them, so all are listed here.. 

Most information on this page is from Tice's book, Dating Buttons..., the pictures are generally from buttons that I have handled.
