On the beach
Southampton bought their 424 new. Spent many happy hours doing 150 exercises before taking my radar rating. Said goodbye to it in 1971 only to find it still going (albeit with new displays) when I came back to the UK in 1987.
Finally withdrawn early nineties when the ILS came into service. Nobody wanted what was left, believe that the displays went for a song to Westlands at Yeovil.
PS add Yeovil and Leavesden to the list of users.
