Just want to show this box since they are not often seen.
Сокол = falcon (brand name), Ловни гилзи = hunting cartridges.
René, very nice box, thanks for sharing. “Sokol” is a very popular brand of powder that was made by several countries along the years. This one shows the logo (falcon head) of the one made at Kazanlak (10). Also, the cases are assembled by Russian “Shevelo” primers.
Just to have all following, the “Shevelo” or better “Zhevelo” means it is “Gevelot” type primers.
Thanks for the insight in the Bulgarian language!
