Halfpenny Green Blackburn Bothas

I have a distant memory of reading (Was it in Aviation News ?) a history of Halfpenny Green which included some photographs of Blackburn Bothas operating as navigation trainers there, in its first year, when it was sill RAF Bobbington.
I have always wanted to find pictures of Bothas at the Green. Can anyone confirm there was such an article, and it’s not just my memory playing tricks on me, and does anyone know where the photographs may be ?
