Hi There....
I believe that Springfield , was a convalescent home C1913-1920'
I have a photograph of my grandfather at about that time , with quite a lot of other gentlemen of various ages.
I think, although I am not certain, that information may be held at the Leeds Archives. I'm afraid I can't put my hand on the details , but I am sure if you google , Leeds City Archives , that something will come up . They are situated at Sheepscar.
Best Wishes
