Thank you Mike.
My apologies for a belated reply. I have been away on holiday.
Thank you for your suggestions. I do have a copy of all of the volumes of War in the Air and most useful they have proved except for numbers of balloons produced.
I will buy a copy of Vol 7 of the Ministry of Munitions official History. I have not seen it before and look forward to mining it for useful information.
All the best
