2nd try at reply (to the list this time !)
I have just spent a lovely Sunday at Bletchley Park....It truly was a wonderful day out with plenty of exhibits (not all computer related) and a fantastic guided tour (that sadly was cut slightly short because of a seasonal downpour)
I was over there a few weeks ago.... (Before it reopened to the public).
Hopefully the computer exhibition is going to expand into this...

but things were yet to be finalized when I was there. There is a LOT of equipment in store (in non-too ideal buildings) including a complete ICL 2966 system.
