My naval hangers are similar to these hangers! They appear to be 'Frankenstein's Hangers'! Mine have the square bits & all but 1 have period gilded aluminium clips crudely pushed into the holes. 1 has an identical brass clip pushed in! I have always considered them to be made up of period parts & fabricated parts!. The buckles on mine are very nice, but worn. Overall, they appear to be put together from many mismatching bits & bobs.
