Hi.  I got this tsuba a while back and have always thought of it as Jakushi School.   I’m thinking later, mid edo maybe.   Do you agree?   It is very intact and great condition.  Measures 8.5 x 8.3cm.   I love the design which is very complex and finely executed with varying shades of gold and silver.  I am away from home at the moment and only have this pic on my phone.   mark
