For what it's worth, here is Chatgtp's identification:
Based on the photo, these are Japanese Kutani-style porcelain bowls, most likely early–mid 20th century export ware, rather than a specific Western factory.
Why Kutani ware (Japan)
Deep cobalt blue scenic landscapes (bridges, trees, pavilions) are characteristic of Kutani decoration.
Scalloped rims with gilt edging are typical of Japanese export porcelain made for Western markets.
The small blue cartouche inside one bowl is a common Kutani motif and often decorative rather than a true maker’s mark.
The lack of a full signature or kiln mark is normal for many Kutani export pieces; many were sold unmarked or with partial symbols.
About the “markâ€
The small blue design inside the bowl is not a factory name.
The faint letters on the base (appearing like “S O†or similar) are not a recognized European porcelain mark and are likely either:
a partial decorator’s mark, or
an inventory/quality mark used by the exporter.
Attribution (best practice)
For selling or cataloging, the most accurate identification would be:
Maker: Unidentified Origin: Japan Type: Kutani ware (export porcelain) Date: c. 1900–1930
The ebay.ai basically said something similar... but then it described my New Hall Two Moths Willow as "Used, Unmarked, Porcelain, Blue & White, Blue Willow, and Glossy... (the piece is from a well known author of blue and white porcelain personal collection). So I'm not "with" utilizing AI on a lot of things yet. But being both old and new at this, my attitude may change. 🙂
Could they be Caughley? Reference: eb item: 168021852402 These, have a different symbol following the "S" but are the same otherwise, (mine have additional gilding as well).
If you are speaking of the "Antique Miles Mason Blue & White Porcelain Tea Bowl Pagoda Pattern" auction that sold on Sun, Nov 30, they do indeed look remarkably similar in all ways but one. The two figures on the bridge are traveling in the same direction on my pieces but the one in the auction appears as if they are facing each other. The "Broseley" pattern decorative trim is similar if not the same on both. The "appearance" of the different directions could be just an accident in placement of the underglaze with a tiny bit of a smudge or it may have actually puddled under the glaze while firing. This could be the pattern and maker I'm looking for. I'd still like to understand the mark to have a better clue.

·8 months agoI can't say for sure, but they look like the Miles Mason pagoda pattern - there is one very similar tea bowl in completed listings.
