Hi Peter.
Nice job with the negatives - credits! I am not sure about the hospital, but there are a couple of clues. No doubt you have already noticed them. The uniform - mainly the cap:-

There are also a couple of photographs with notices displayed. One with an ambulance delivering a patient, and one with a nurse with an opthalmic ward patient:-

But the notice may hold clues. The photo's look 1950's to me - the ambulance - and the seams in the stockings. I must be getting old as the first thing I checked was were they straight! (With due respect to the ladies!).
All the photographs are a superb addition to our history Peter. Lets hope that someone can identify the hospital...
Will.
