From Wikipedia;
The Centurion Mk II ARV consisted of a basic tank hull with a box-like superstructure in place of the turret. This accommodated the winch and a separate winch engine, a 160 hp Rolls Royce B80. The winch engine powered a generator providing electric power to the winch. The cable emerged from the back of the winch housing and a rear mounted spade gave stability whilst winching. The vehicle was used by Australia, India, Israel, the Netherlands, Sweden, Switzerland as well as the United Kingdom.
The first prototype of the Centurion Mk II ARV was developed by the Fighting Vehicles Research and Development Establishment as the ARV FV 4006 and completed in 1952–53. After user trials, the first production vehicles were completed by Vickers at Elswick in 1956–57. Some Mk 2's used the hulls of former gun tanks or tugs but most were newly built as ARVs.
From 1956 to 1960, the Swiss army bought 30 Entpannungspanzer 56 Centurion. These were used until 1991 with the numbers M + 78601 to M + 78630. In 1988 the first ten vehicles were scrapped.
