Bill - appreciate your input as always.
Acquired your book recently, and would complement you on high quality production and worthwhile addition to the library - but why isn't this vase shown in your book
I think we do realize that SEA and Aseda are/were separate outputs, but thanks for the reminder - also believe that we covered this somewhat earlier in the thread.
Very unfortunately, the vase in question lacks any kind of marks which a bit irritating, as this always hampers effort to locate provenance.
However, your further research would be very welcome, and hope we may eventually run this one down.
Kind regards to you Paul S.
