About 5 grooves Zouave rifles

[Oviedo Minié]

Hi Friends :

after some years researching about Zouave Rifles History in order to write an article, I know why and what for 3 and 7 grooves patterns , but I can't find the same answers for the very rare 5 grooves pattern... someone can tell me something about that subject ?? Or where can I look for it ??

Thanks in advance
