Don
Thank you!
Is there any chance at the "Patent Greatest Angle Clamp" paperwork. Undoubtedly a UK patent but there is no associated patent number with this one. The patentees will be the same as 17840, if that's any help.

Heath may have applied for the patent in 1909 but did not receive it until March 1910. It was patent no. 17840. Does your sextant actually say "Patent 17840" on it? Mine simply says "Patent" on the tag on the front of the clamp mechanism and on the back of it.
Attached is Heath's patent.Don Seltzer
