Built as a C170B, this aircraft made its first flight on 29 January 1954 with the 'trade plate' rego N2587C. Somewhere along the line it also seems to have briefly been N11B but the following month it was delivered to the Royal Thai Air Force. Ten years later, in 1964, it was transferred to the Thailand Ministry of Agriculture with civil registration HS-RAC. In 1970 it was sold to Sky of Siam Co. and re-registered HS-CHC. It was later exported to Australia where the rego VH-YCS was allocated but not taken up. It was subsequently restored and registered VH-COS(3) on 17 December 1997.
