Thanks for the replies but i am a bit in the dark as i cant see the characters correctly in the replies - my browser ie8 is supposed to have the language packs installed but it just not showing up right - are we saying that all four characters combined mean seikanenzou??
I dont think it is an old piece, it shows some warriors swordfighting, is a nice vase, am just interested to know the translation for completeness, i never had one with an inscribed mark before.
edit: I see that if i choose reply with quote then the characters are shown in the editor window at least
