77th Special Forces Group DUI/DI/Crests, HM "Denmark NY 6D"

This is an early pair of 77th Special Forces Group crests or distinguished unit insignia, hallmarked Denmark N.Y. 6D. Originals have become very rare.
Please look at the pictures closely before bidding. The crest on the left has had some reinforcing done to the posts. Both crests are in very good solid condition.
