9 mm Flobert with SP headstamp


here is an argentinan ctge with its box
i found reference to this ctge in George Kass book.
The label is slightly different.
But the big difference is the fact the base is not copper, but like stained brass (not nickel coated)
It is the first time i see such a base
PS: Vic do you need the ctge?
Powdertin do you need the ctge ?
