RARE POST 17th C SINO-THAI CANTON ENAMEL STEM BOWL maker's mark ON BOTTOM

Description

I am not an expert so please do your own research. THIS PIECE HAS BEEN INDEPENDANTLY RESEARCHED AND IS AN EXTREMELY RARE EARLY POST 17TH Century SINO-THAI CANTON ENAMEL STEM BOWL.....
Elegant Stylized Dragon,
post 13th - 14th century, with scales, extended horns, feathered tail.  Additionally it has 4  toed claws indicating it was for a high official.
K’ang -Hsi rein,
1662-1722, added whiskers and depicts it chasing the flaming, the symbol for treasure, enlightenment and accomplishment.  This piece should date during or after this reign.
Sino Thai Canton enamel stem bowl is extremely rare
..
Rare that many might have been made but few have survived
, with apparently no example in the Nation Museum in Bangkik and no mention of this particular form in the only reference publication (Robinson).  One further reason for the rarity of this piece is that most of the enamel wares exported to Thailand were of Tai style. While this is of Thai shape and use, the decoration of the dragon in clouds is decidedly Chinese.  Also rare is that the maker's mark  on the bottom actually includes the address.
The inscription has been hand written in overglaze enamel in standard written Kaishu script.  The characters would have been read starting from the left hand column as follows:  Chung Hua Kuo Kwang-tung Sheng-ch’eng Hao-p’an Chieh Yi Ho Hsiang Sheng chih.  The translation of this mark is : made by Righteous United Fortunate Abundance, Ditchbank Street, Provincial Capital, Kwangtung, China.  The form Chung Hua Kuo is an old description of China.  Kwangtung is the coastal province in the South now known as Guangdong.  The Provincial capital is Canton ( now known as Guangzhou).  The name of the firm which made the bowl is
UI HO HSIANG SHENG
.  From Ming times China produced export wares expressly for sale to Thailand mostly sent through the port of Canton.  Much of this trade was in porcelain decorated in enamels in the Thai manner.  From 1683 enamelled objects of a copper base and in similar forms to the porcelain ones were made at Canton for the Thai trade.
This bowl is in surprisingly good condition. It is by no means perfect. It does have some chips and crazing. I have tried to gather pictures of this bowl (BELOW) in a realistic photo collage for your reference. It is a bit loose on the stem but sturdy enough to stand on its own. see all photos for condition. THIS PIECE IS A ONE OF A KIND PIECE AND SHOULD BE HANDLED WITH DELICATE CARE. IT WILL BE PACKED IN A STURDY, LARGE BOX WITH PLENTY OF PACKING MATERIALS.
There is no similar bowl to this from Robinson reference.   References on accumulated information are furnished upon request.
PLEASE NOTE ALL THE ANCIENT MOTIF THAT WILL DATE THIS PIECE AND STYLIZED DRAGONS, ETC.
THIS PIECE MEASURES APPROXIMATELY 4 1 /2 INCHES TALL x 7 1/2 INCHES WIDE AT THE TOP. THE BASE IS APPROXIMATELY 4 3/4 INCHES WIDE.
