The 'E' Type Forum

Can anyone tell me how to remove the key barrel from a 1969 Series 2 T type? Dr Google tells me there is a small hole in the casing and if you insert a pin, with the key turned to Aux, the lock pulls out but I can't see a hole. https://i.postimg.cc/sgQQQ0PZ/IMG-2426.jpg https://i.postimg.cc/Z5BBBDPr...
