Executed in classic T-frame with protractor up to 90º and ivory vernier.  
Beautiful protractor, made out of one piece of ivory, white as show with no colorations.

Mid-18th century these and similarly large octants were introduced as successors of the backstaff/Davis quadrant.
On ships of the Eastern Indian Company between 1747 and 1762 there usually was just one such octant on board.
The octant was considered a very luxurious and expensive instrument,

A captain’s wage was fl. 72,00 per month, a mate earned fl. 26,00 and a deck hand fl. 8,50.  
Most crew members had to work several months to save such an amount.
