Maybe, - I had them down as football pitches - The big AA gun site in the area was just the other side of the Maypole at "Kings Wood" - Moundsley Farm , in the triangle of land between Crabmill Lane and Druids Lane. The same photo mosaic shows that site clearly. It had 4 of the big 3.7 AA guns in emplacements with the "predictor" emplacement looking like a 5th on the photo. - A standard layout for such a site. There was hutted accommodation for the gun crews to the West of the gun emplacements and a Motor transport compound to the North. With the gunsite at Kingswood and the big RAF base at Wythall I'd imagine the football pitches at Daisey Farm recreation ground would have been in high demand - maybe more mud than grass! Giving rise to the "blurred look". - If there were any guns on Daisy Farm Rec, I'd imagine them to be the smaller 40 mm Bofors, and would have been there for only a limited time, as they tended to move those around.
