Trevor, I presume you mean 1960 not 1970?
VAC - Vickers Armstrong, Crayford.
It bears a strong resemblance to an L32 fuze (other than the nose profile which is more akin to a No. 700). The L32 was introduced for L13 gun of the 105mm Fd (SPG Abbott). Although the Abbott didn't enter service until 1965, design of the vehicle and armament had started in the late 50s. The vehicle was designed and manufactured by Vickers. Initially, the ammunition utilised US designed, UK manufactured fuzes. Which is hardly surprising as we were using the 105mm How. which was introduced in 1961 and this used US designed, UK manufactured fuzes. Later, UK designed and manufactured fuzes were utilised.
