9 x 21 IMI Fiocchi hds. variations

While recording data for my 9 x 21 IMI database, I found 5 different Fiocchi headstamps.

They differ for spacing between letters/numbers and letters/numbers dimensions

Have also a Fiocchi headstamp where the “F” letter is partially stamped, but I think this is simply due to used bunters and not consider it as a headstamp variation
