Saddening story. I had the chance of visiting Bletchley Park and the Museum about a year ago, and the rebuild of the Colossus [1] is definitely a highlight of the exhibit — especially. All the volunteers I met seemed fully dedicated to their educative mission.
There is so much history in that place, and so much energy for hoarding, preserving, and showing those marvels to the public, that I really hope it can remain as welcoming and entertaining as it was when I visited.
