As promised earlier I sneaked past the cave bear, step over the sleeping saber tooth cat and throw a mammoth bone to the Dire wolf and recovered the address to the Centre des Archives de l'Armement et du personnel de Chatellerault. This is the last address I have and it is about six years old so no sure if it is still valid. But here goes: 211, Grande-Rue De Chateauneuf, B. P. No. 650, 86106 Chateauneuf Cedex FRANCE. Remember all replies from them will be in French. Good luck. Oh by the way I just GOOGLED them and here is a website
