Hi Tim, here we go.
Yes I can confirm the maker's mark being for Paulus D'Hont, born around 1774 and became master in 1803.
Middelburg between 1636 and 1785 used three standards. Het Grote Keur or First Standard; 10 penningen and 18 grein, and Kleine Keur or Small Standard often called 2nd standard; 10 penningen 16 grein. In 1696 a third Nieuwe Keur or New Standard introduced; 11 penningen 8 grein.
In 1785 Middelburg lowerd the three standards. Nieuwe Keur or New Standard; 11 penningen and 2 grein. Grote Keur or First Standard 10 penningen and 12 grein. Kleine Keur or Small Standard 9 penningen 12 grein. The reason why Middelburg lowered the fineness of the standards was due to the price of silver, shortage and high demand for silver and gold coins to pay for the Fourth Anglo Dutch War (1780–1784) which proved a disaster for the Netherlands, particularly economically.
For the mathematics
1 penning = 83,333/1000
1 grein = 3,4722/1000
Back to your purse frame being Kleine Keur or Small Standard after 1785 equals 9 penningen (9x 83,333= 749,997) and 12 grein (12x3,4722=41,666) together 41,666+749,997=791,66/1000 fineness.
