Shakudo nanako kozuka signed "Ishikawa Nobuhisa" with NBTHK Hozon Tosogu. Unfortunately I do not know anything about this maker. Therefore we can judge it based on workmanship alone.
It is made of very high quality shakudo with great nanako. Wild geese is covered with thick layer of gold foil and decorated with shakudo eye. Tree trunks and leafs are very well executed. Design is elegant and simplistic. This is really a great piece to appreciate.
Made in late edo period.
