A slightly later map, 1920’s has that area The Pheasantry, already built on, in the angle of Sheepfoot Lane and Middleton Road.
Glazebrook Ave and Perrivale Road. etc.
I have heard there was an Army training camp there ,in WW1 .
Hope someone has some info for you.

PS,the sand pit would be a good place for a gun range.
