These are from Plates dated 1805 from an album labelled: Vorstellung der vorzuglichsten Gattungen des Türckischen Militairs und ihrer Officiere in The Vinkhuijzen collection of military uniforms, NYPL

Although two of these plates are copied from:
The Great Lord in ceremonial dress for the day of Beiram, after Jean-Baptiste Vanmour (Van Mour), 1671-1737 and Sadrazam, the Grand Vizier, in Ceremonial Dress and Turban, after Vanmour which date to circa 1699-1708, there is nothing to indicate that others date to anything other than 1805.

This uncropped version has a caption that indicates it is a Deli (scout), so not a sipahi.

Sipahi or Turkish Cavalryman after Jean-Baptiste Vanmour (Van Mour), 1699 to 1708
