A very similar dagger was sold through these Rooms 28 April 1998, lots 122 and 123, the first of which recently re-appeared and was sold at Sotheby's London, 18 April 2007, lot 157. Both examples were dated AH 1207 (1792-3 AD) and were attributed to Zand Iran. Similar enamelling is found on three daggers in the Khalili Collection that are attributed to Ottoman Turkey (David Alexander, The Arts of War, London, 1992, nos.87-89, pp.146-149). A jambiya with closely related enamelling signed by Mahmud and dated probably 1179/1765-6 is in a private German Collection (Oriental Splendour, Hamburg, 19993, no.146, pp.206-7). The enamelling is also similar to that on a group of zarfs many of which are signed and dated, such as one signed by Taqi and dated 1174/1760 in the Keir Collection (B.W. Robinson et al., Islamic Art in the Keir Collection, London, 1988, no.M.19, p.134 and col.p.34).
