Yes Australia also converted the Radar AA No.3 Mk7 to mortar locating, until they were replaced by American radars in ViteNam.
The Radar AA No.3 Mk7, was withdrawn from Australian Heavy Anti-Aircraft Regiments in 1963, when the regiments were coverted to Light Anti-Aircraft and thence disbanded, into field regiments, 25 pounders.
Does anyone know where to get drawings to enable the making of a scale model of the Radar.
Because the 3 Mk7 was "British" there are no drawings available in Australia either from RAE (Engineers), RAEME (electrical, mechanical engineers) or RRAA (Australian artillery) museums.
