Seems like our 1920s/30s proposition is much more likely than the 70s or 80s one.
I think we are getting closer with the information provided and at the same time individual points are still in debate. May be a little structure will help us close some points. Please add bullet points if you feel there is something missing from the list.
Points currently under debate but not agreed upon are:- The pottery artist
Are we all comfortable and sure that 蒋永西 is the master that made the pot? If not please add new findings. If so, what is his name in Roman writing?
If we agree, than we are looking at a manufacturing date ranged between 1900-1957. If my assumption is correct based on the link provide by MarshalN... (Note: My Chinese skills are zero, so I picked up what I can read)
How is this artist ranked, is he well known? Are there more examples of his persimmon pottery. If so, please post links so we can all compare and zero in on the details of his craftsmanship.- The calligraphy artist
Kyarazen found that this master (蒋永西 (石生)) was a potter and calligrapher. May be hard to determine 100% but can we make assumptions on one hand at work in this creation?
If not, is there a way to link this master to a known collaboration with a calligraphy artist? Please let us know if this is typically not under evaluation when identifying/dating genuine Yixing artwork. - The ball filter
Is there any (photo) evidence of a ball filter being used in the date range between <1900-1970? If so, can we determine a "date from" which ball filter (persimmon) pots were produced. If possible: by this artist.
(Note: Not when ball filters became common but the possible "starting" point)
Thanks again for all your energy and excitement.
