Dolphin's Armor medieval helmet - photos

[Okapi]

Sorry Mike, it's not a detail, it's like you use the name "Jean" in french for an "jean", one is the title for a person, the other is a cloth, nothing as a criticism, just calling things by their right name, if you make a search with "dolphin" you never can found who is the "Dauphin" with a capital at the first letter in France and other royalties, there are two totally different things.
Nothing to do too like with the spectacular work of steel "damasquinage" in french(for this helmet) which has nothing to do with the word "damas", the two are made for qualifying steel and are steel but are totally different in technique and result. ;-)
