20mm T.C. french case for ID

[Przemek]

Hi

I look for informations about case from photos. T.C. - Tir Canone? S.F. production [Sociéte Française des Munitions],
1907, and Polish [!] stamps [re-elaboration in Poland] S8 in owal [officer stamp].
Diameter bottom - 31mm,
Calibre - 20mm ~1mm
Length - 118mm



I watched it at 100% on some board [meybe Francaise], but I can not find :(

Thanks

Regards
