I have some berdan primed hulls from both Alcan and Fiocchi.
I bought a set of mostly new unfired unloaded paper hulls in gauges 4 through 410 a few years ago at the Chantilly show. The 24 28 and 32 gauge were Civlio Fiocchi Lecco with Berdan primers.The 4 8 and 410 were Gevlot. The 10 and the 20 were Alcan.
It was missing the 12 16 and 6.
I still need a 6 gauge to complete the set
