Was looking on a few French web sites (thank you google translate). Apparently, the grandson of Aime Maisonnial was answering some questions about his family’s guns. He is quite proud of them and still has an order book of the guns they made after the war. Unfortunately the earlier book was lost. He recommend this book. The Armory of St.Etienne Unfortunately for me it’s in French. However, I know some of you do speak French and I thought it might be of interest.
