Koboshi kabuto Samurai helmet with standing rivets

Mid Edo Period, 18th Century

Rare eight-plate kabuto with seven rows of twenty-five rivets each for a total of 1,400, which get smaller as they get closer to the peak of the helmet. The plates' edges and the profiles of the visor and fukigaeshi are covered in golden brass, with a six-tier tehen no kanamono of various metals and colors at the top. 

Eyebrows and wrinkles are embossed on the visor (mabisashi). 

The komanju shikoro is uncommon, with five kiritsuke-kozane plates and a sugake-odoshi binding, which is rarely connected with this style.
