A personal Bletchley Park anecdote: my grandfather, an electrical engineer, staffed a radio listening station during the war, and every evening a motorcycle dispatch rider would take the day’s intercepts away to a secret location. It was more than 20 years before my grandfather figured out they went to Bletchley.

In the 1980s the Bletchley museum project put out a call for wartime electrical components so they could build their Colossus replica. My grandfather in the 1950s had made a chain of Christmas tree lights from govt issue tiny light lightbulbs he pinched from work. He painstakingly removed the nail polish he had painted them with 30 years earlier, and sent them to Bletchley. They used his family Christmas lightbulbs in the replica that is still there today.

I had the privilege of touring the museum with him in the 1990s. Also on that day I heard my grandmother’s stories of her time in the British Army during the war. That day was incredibly interesting and moving, and is an important memory for me.

What an incredible story, thank you for sharing.

At the end of 90-s some parts sent to the Russian Mir space station were found and bought at flea market - these parts had been pinched from work and their production ceased during those years of collapse in USSR/Russia.
