I lived in Ashgate Avenue until 1957 and I remember, now you have jogged my memory, there was a brickworks with a tall chimeny over the field at the bottom of our garden.
The Inkerman was at the left corner of the field and there was a footpath leading alongside the Inkerman to Ashgate Road. You can see that, although the Inkerman has been filled in, Inkeman Cottages remains.
I would put the brickworks around the south end of the field which remains, just east of what is now Rockingham Close. Looking from our garden the Inkeman was out of sight far left, probably 150 yards from the bottom of the garden. We kids used to play in that field which is now the housing . Direct in front over the field was the quarry used for the brickworks, without water.
If I unlock any other memories I will post.
