Bakehouse or Aller Pottery mottoware pot, A mark in circle - prob Aller

Which pottery made this lovely retro pot?

Aller pottery Bryan Newman. Just checked the finer details fron one I have. Definitely Aller

Aller is normally in a square although there are a few in a circle. Bakehouse seems more likely but I've not come across any with an A mark, so must be Aller (just to add, Alan Peacey used a similar circular A stamp in the late 60s, but on earthenware)

Thank you
