Other than a brief mention on Richard Binder's site, I really can't find anything about these pens. There are French Filling is with a standard button filler and pressure bar The largest has an 18K nib with the Globe D'Or logo The middle is apparently WWII era with a steel nib marked Globe D'or and 1944 with a ribbon banner motif The smallest pen is imprinted Atoma (I assume atom for the small size). The nib is a warranted 18K. So likely French, but not clear if original.
