This piece is close in form and style to the British Museum indicator, but is likely to have been made in the nineteenth century. A further Qibla indicator dated 1151 AH/1738 AD is in the Museum of Islamic Art, Cairo (MIA3348, illustrated in Porter 2012, p.36), and another sold at Christie's London, 20 October 2016, lot 183.
