Dreyse 1907 help

[Kaiser715]

I recently picked up a dreyse 1907 on a whim however it has one glaring issue. The striker tip is broken off, fortunately I found someone who can repair it but knowing the overall length would be of great help. Would any of you be able to give me the dimensions on the correct length for the striker? Thanks in advance

If the repair consists of grafting on a new tip, just leave it long and adjust the protrusion in the normal manner.
