WW1 French F1 fuze query

[dano1917]

On the left is a WW1 French F1 grenade with the slow match fuze. On the right is another French WW1 F1 with partial fuze. Is this the percussion fuze base or a variation of the slow match fuze? Dano

Hi dano, could you post pics made of the top of the fuze from above?
