No. 3 & 4 Aeroplane Supply Depots France

[Grahamgrasshopper]

Hi there

Can anybody tell me about No. 3 & 4 Aeroplane Supply Depots France?

My Grandfather was an Aerial Gunner with the RNAS during the Great War and according to his Service Record after being transfered to the RAF he served at No. 3 ASD and then at No. 4 ASD. I think No.3 was based in Guines France and No.4 in Courban France.

I am trying to write a little book about my Grandfather's time during the war but I am finding very difficult to find any information about the ASDs to finish my project. Could someone tell me what the role of these depots were? were they based where I think they were? What was the responsibilities of people sent here? Where can I find information on the web?

Many thanks for any help I may receive.

Graham
