Inert Citron grenade.


Well-Known Member
Hello all,
I've at last completed the inert, reproduction mechanism for the empty Citron-Foug case for display. I would like to thank all the members who sent me drawings and pictures without which I would not have been able to make it as I had absolutely no idea how it worked!
The cap/fuze, and det were cut down from an inert training 36 grenade. The inert det and fuze glued together with Araldite, and the det coloured with a blue felt tip pen. The remaining piece's made from scrap brass, and the wood from a broom handle stained with wood stain. Spring from an old biro.
I must emphasise that this display piece is completely inert and contains no traces of explosive or primer at all. I'll like to welcome any criticism if it's an unrealistic repro, but it's been an interesting project and kept me occupied!
I'm hoping that the pictures I'm posting will show how it was made, Iwill have to post them in two lots as they wont all fit.
1. Broom handle.
2+3. Starting on the dummy striker.
4. Deciding how best to assemble it.
5. Washer, Top cap, from scrap brass, inner plug more broom handle.
6+7. Assembled unit.
8+9. Completed with three brass pins.

Fantastic :congrats:. How about making som for us other to? I could realy need a repro fuze for my Citron.
Very nice job, nice to see someone else who likes making bits to restore their ordnance.
Inert replica fuzes

Hello Freaky,
A good way to make an inert, dummy, fuze/det is to use a piece of brass tube or a cylinder turned to the correct size on a lathe. The fuze is simply a length of shoelace filled with strands of string, and glued into the cylinder, painted or stained with ink. The crimp can be mimicked with a simple electricians crimp tool. Hope this helps,

Great restoration but the original top 'keyhole' plate was made of tin not brass.

Thanks John,
I was aware of that but thought I could use brass as it's bound to be taken to bits for a look inside many times by friend collectors, and brass would survive better. However it's been on my mind and I'll probably replace with a tin one when the novelty wears off!
Very best wishes,
You just need to make the tin plate cover now !!:tinysmile_fatgrin_t

Hello Paul,
That's the next piece to be done. I've seen various types, rounded, conical, etc., so when I've made my mind up I'll solder up a tin one. I try to have a few projects going on at the same time, it's stops me rushing impatiently and spoiling the job! Old navy saying; "Don't spoil the ship for a halfpenny worth of tar"
What a great job on making that repro percussion fuze of the Citron!!!

Here are some more details about the Citron Foug:

The wooden fuze plug was held by three small wooden rods in the grenades body. The holes of the rods were sealed with wax. The same for the protective tin cap; it was placed on top of the fuze and was sealed with wax too.

The color of the Citron was either without any paint or horizon blue. Here we have the same discussion as metioned in another thread about the "real" color of german fieldgrey. The french standart color of WW1 can range from grey, blue-gray to light blue in different shades.
