thanks gyrojet and betmawa89!
Very interesting - the box with the stamp from 10.4.1916 is also shown in the famous Parabellum book from Görtz and Sturgess (Vol. III, page 1477).
The other ones are new to me.
@betmawa89: can you elaborate a little bit more about these sample books, especially are they produced by M+F, when, do they cover also other rare boxes, e.g. for proof or dummy cartridges?
