Kindly asking for your assistence in identifying the maker's mark on this presumably French or Belgian cutlery. It has the 84 stamp on the right side of the pieces, flanked by a square maker's mark reading what I believe is "R.C" beneath a ball/globe/balloon of some sort. In some pieces, it looks like the letters are "R.I.C" although the I could also be some kind of stem, and the globe forms a tree, or a balloon with a rope beneath it. I haven't been able to find any reference to this mark. The pattern, too, I haven't been able to locate. Any help would be greatly appreciated!
