Yeah, a cockeyed optimist. Me thinks they were a firearms merchant in Sarcelles but may have advertised as A.M. Mainwaring, Paris. Some may have used their name in the same sentence as Gastinne-Renette. Were G-R close or in Issy-les-Moulineaux??? Or did they have a factory there and then retailed in Paris where the money was.

Kind Regards,
