Fiocchi 9 mm Blanks are found with a number of different headstamp or other variations. To my knowledge, they are all brass case and are one piece - no separate “bullet” (acuttaly the reduced diameter forward portion with rosebud crimp.
G.F.L. 9 M 3 8 67 (Long crimps, red crimp seal, nickel primer cup)
G.F.L. 9 M 3 8 70 (Short crimps, red crimp seal, nickel primer cup)
G.F.L. 9 M 38 70 (Short crimps, red crimp seal, brass primer cup)
G.F.L. 9 M M (Long crimps, no crimp seal, brass primer cup)
G.F.L. 9mm (Long crimps, no crimp seal, nickel primer cup)
There could be more, for sure, but those are all I have. I do have one very minor variant of the last one listed, that has a slightly shorted “case” (from head to mock case mouth) and the primer crimp lobes are not so curved, but rather straighter, somewhat like a truncated bullet might be. Very tiny variation, but I decided to keep it anyway.
The round with the capital “MM” is the same headstamp that appeared on ball rounds sold (and likely lighter loaded) in commercial 9 mm Glisenti-labeled boxes. I am NOT intimating that particular feature makes this a “9 mm Glisenti blank.” Simply an observation.
