   From the image it looks more boxwood than metal. According to Rees, George Atkins was London based (1807-1810 Fenchurch Street & 1811-1812 Little Charlotte Street) mathematical instrument maker. The same- looking rule appears in a Tom Martin’s article in the Spring 2021 (vol. 30) edition of the JOS (page 13). According alcohol oracle Tom, it is based on Matthew Quin’s slide rule for his universal hydrometer. David Rance
   The National Museum of American History has a hydrometer (item PH.330585) marked “G. Atkins Fenchurch Street London” with a wooden slide rule of a very peculiar design.
   According to the NMAH George Atkins was a mathematical instrument maker who had a shop on Fenchurch St. by 1804, and who later worked at other addresses.
   In 1815, George Atkins became a partner with Mr. Myles Brockbank, clockmaker. Andries de Man
