I do have the same white QS-Box, but with an Overlabel, saying:
Via S.Agostino,9 Bulciago, Lecco, Italia
Lead brass plated Ball rnsfp 4.5g. Year 2009 L.n.201050509
Sign of the italian Proofhouse, and underneath:
Means, there are drawn brass cases with G.F.L. 7 PENNA headstamps AND on the case a sidewards circumferal impression: 7 penna QS…
This circumferal markings are necessary by CIP rules, because the headstamp indicates usually the maker of the ammo…but as Fiocchi is not the manufacturer of the whole ammo, the loading company (in this case QS) has to put their markings on the case…
and, may you can tell me, why they have such an odd number of ammo in this boxes?? (65 pieces??)
and so my box,must be the intermediare box between yours and the black box…(fully loaded by Fiocchi) ??
