Hello, maker is Edmond Jamet, Paris, 15 Place Dauphine, active 1831 to 1847. The "1" refers to the silver fineness, the "premier titre" of 950/1000 parts silver. Best wishes, Bahner
continental flatware is much more substantial than north american. perhaps it had to do initially with the relative scarcity of silver, which accounted also for the american flatware's thinness. i've wrestled with a few sets of silver that would intimidate an elephant. around here, they are an endless source of amusement for our children.
