HAUXHURST & DEMILT fusee pocketwatch

I have a HAUXHURST & Demilt fusee pocketwatch from the late 1700's? Silver case- porcelain dial- heavy engraving- has what I think is the hand colored watch papers inside with very old cursive script handwriting- I cant actually make out the words- Nathaniel Hawxhurst (Hauxhurst) and a watch by Haushurst & Demilt from the late 18th century is known, as are watches by Hawxhurst. I read somewhere where they were also firemen of Engine 18 in New York - which they along with 15 or so firemen purchased with their own money! Anyone else have some of their work?>
