My father was stationed there during the war.....
Many fond memories of the area...
They had a temporary exhibition a few years ago, that was supposed to be converted to a smaller permanent display, about its role during the war .. My dad sent them some pictures, his library card, and some other memorabilia on loan for the duration....
Not sure if it still exists though. I haven't heard back from them recently, and he asks me periodically about it. (He's 99, my mom 95, married 73 years this Oct 12).
If anyone visits Bletchley Park, I'd appreciate an update...
