In May 1940 there was a standby reserve of 18,000 aircraft bombs of 200kg, filled with 61 liters of Phosgen ("Produit No 5") weighing 90kg, instead of their explosive content.
The filling took place at Aubervilliers near Paris in 1932 and Pont-de-Claix (Isere department) in 1937, but the bombs were stocked at Plaisance in the Landes Department.
The bombs body were regular 200kg bombs body and there were quite a number of problems due to that, as they were not hermetic and there was problems of leaks of Phosgen.
These bombs were painted in pale green with a stamped +C for phosgen (or stamped +5 for the older produced bombs) and white markings (3 lines: Code indicating the nature of the Filling, Place and year of filling, Filling lot number.
They were stocked in olive green (or pale green) wooden containers with white markings.
The "pale green" and "olive green" refer most probably to the local variations of the pale grey green colour that was chosen as international colour for chemical bombs and shells in the interwar (often also used for smoke bombs).
There is also mention of 1kg "grenades d'aviation", produced in 1935 and 1939, filled with 0.14 liter of Yperite compound, unpainted ()therefore natural copper or lead colour depending of the nature of the production) but with their dispenser (Chargeur V32) marked with a Death Head and Crossed Bones marking and a longitudinal green band 50mm wide.
The production went on during the French Vichy governemnt, with a few hundreds of additional bombs stock-pilling at the chemical factory of Pont-de Claix (established in ww1) and the military facilities at Lannemezan (of shameful fame as being the site of the concentration camp established there by Vichy for Gypsies and other "nomads") that were in areas under exclusive control of the French Vichy government - Aubervilliers and Le Bouchet being in the German controlled zone).
On the war collaboration i this field between the French government and Nazi Germany we have some disturbing indications, with a mentions in French archives (AJ/41/554) of a "lease of 30t of phosgen to Germany" in 1942-43 and "production of aggressive substances for Germany in 1940-43"
10kg Brandt was more probably a mortar "bomb" (the term "bombe" was widely used by then for designating mortar shells)
50kg DT bombs body may also have been filled with other chemical warfare compound - They served for instance for the pre-series testing production of liquid incendiary bombs in 1940.
