Proof ctges

Hi Jean-Pierre
Nice box do you have the contents?
My balkans knowledge is fairly patchy but even I can see this box appears to have two manufacturers lot codes as opposed to the one you normally find.
PPU 8801 Im happy with - normal Prvi Partizan marking for that period
The second one SPV (which I assume is the powder manufacturer) is it Slobodan Princip Vitez. If so I presume we dont see boxes made like that any longer?
