THIS IS AN UNUSUAL LOOKING MATCH SAFE AND SOVEREIGN HOLDER IN THE SHAPE OF AN OPENING BOOK.

 I BELIEVE THE COVERS OR LIDS ARE SILVER PLATE BUT I CANNOT FIND ANY MARKINGS WHAT SO EVER OTHER THAN A REg. NUMBER OF 594453

IT HAS A STRIKER PLATE DOWN THE LENGTH OF THE BOOK OPPOSITE THE SPINE 

IT IS 45mm X 35mm X 15mm IN SIZE ++++ PLEASE JUDGE FOR YOURSELF FROM THE PHOTOS
