Thanks! I find only Bulletins 1-28, 45, 50, 51.You are welcome WESTLAND.
There is also a series of publications that can be found online, produced by the UK Ministry of Supply, that began in about 1936 and continued through WWII. They were called Ammunition Bulletins, and there were a fair number of them (45-50?). They covered many different types of expendables, including small arms ammo, artillery projectiles, mines, bombs, rockets, fuzes, etc. There were often sections at the back of the Bulletins that covered foreign munitions including the French stuff. IIRC there were several that were dedicated just to foreign ammunitions. I think that there were French bombs described in there somewhere.
On a bombing mission, the 75 kg G2 bomb (corresponding to a 155 or 152 mm naval shell "dressed" aerodynamically to be launched by plane) being carried under the belly of the plane. The I2 bomb was a 150 kg bomb which corresponded to a 203 mm naval shell.
The 75kg G2 and 150kg L2 bomb had a large explosive charge (63.7% 102 lb) and (67% 224 lb), so could not have penetration against ships.
So what was the mission against ships? only "external" damage?
