I came across a rank on a QSA today that I hadn't seen before. This QSA is for sale at the next Bonhams auction and is named to Amb. Agent Tara Chand. Ambulance Est.
According to the write-up, Tara Chand served in charge of the Dooly Bearers of the Ambulance Establishment Bengal Command. He is confirmed on the roll as Second Grade Ambulance Agent and is noted as receiving a silver medal and the only one with a clasp.
