Similarly I have flats from Conquistadors, infantrymen and cavalry, but I ignore who is the editor and whether there is a catalog:
The identification of the figure is "Ms YY" or "MS YY" YY are one or two digits, and the editor is a letter 'L' ronded on the back side of the flat base.
Can anyone help me. I have some 40 flats of this group.
Thank you.
