That photo of Colossus

In this, the week of the 75th anniversary of Colossus tackling its first Lorenz message, Steve Cockayne tells us what he overheard in a conversation that his mother was having at a Bletchley Park reunion a few years ago. I took my Mum, Lorna Cockayne, to a Bletchley Park veterans’ reunion a few years ago. The next day we went to BP and there was a demo which was recorded and then afterwards I got Mum and Dorothy to stand by the Colossus Rebuild and took a few pictures.
