Hi Kino,
thats a really nice Takouba

The hilt, although probably very recent, is much better quality than on many Takouba made mid 20 th C onwards (I really like it

) The blade seems older ....possibly late 19th C - early 20th ( others could give you a more accurate age)
It is very common for older blades to be re-hilted...sometimes the blades are over-cleaned (to make them look newer) so all the patina is lost.(It seems it's just 'us' that like our blades old and rusty

)
Regards David
