Hi, Elvis!
Tough to say. Some makers of flats marked the bases, many did not. Some cam be identified by the shape of the base. That is, one maker used a diamond shape for his bases;another used an oval shape. There are books that include illustrations ofthe bases to help identify the maker.
Judging from the quality of the paint, I'd say yours are relatively recent, from the past 20 to 30 years. One place to look is at Berliner Zinnfiguren. They still produce their original catalog of figures, started by Werner Scholtz back in the 30s. And they carry other brands.
Yours are all French Napoleonic figures.
Prost!
