Although the seated British soldier in this battered but content-rich cabinet photograph displays no apparent hint as to his regimental affiliation, the answer to that question may be found on the pagri or turban of the Indian man.
Wearing primarily civilian attire, the Indian man's headdress appears to be of a regimental pattern. It actually bears a pagri badge in the form of a rearing horse above a small scroll. Feedback from members of the SofthQ Facebook group seems to indicate that this particular style of badge was worn by regimental servants employed by the King's (Liverpool) Regiment while it was posted to India.
The 1/ King's was stationed in India between 1902 and 1908 while the second battalion was there from 1877 to 1890 and again from 1908 to 1919. The pattern of the soldier's foreign service helmet being held by the servant would seem to indicate one of the two earlier time periods.
