I want to ask question about this Tsuba ( My first impression was Owari district sukashi tsuba )
The size is 65 x 62 mm , the thickness ~ 3,5 mm
The surface has a dark silver shine - cast copy ?
Tsuba has numerous granular tekkotsu - best seen in mimi .
The theme of this tsuba is Miho no Matsubara - seashore with beautiful pine trees and scenic view of Mount Fuji , the design is rather rare.
In the book "SUKASHI TSUBA" by Kokubo Kenichi 1968 I found a similar tsuba .
Could it be Kanayama tsuba?
