early model Jarda :



Description: These grenades are similar in all characteristics except size. These grenades consist of a thin iron or steel casing, or head, containing the explosive filler, which is screwed onto a hollow wooden handle, through the center of which runs a double length of cord. This cord is attached at one end to a lead ball which is part of the igniter, and at the other end to a porcelain ball. These grenades use igniter B.Z.24 consisting of a lead tube or sheath connected to a threaded brass fitting by a short steel tube. The steel tube is threaded on both ends and contains the powder delay pellet. The lead tube contains the copper capsule which holds the friction composition. The friction wire is cast in the friction compound contained in the capsule being coiled at the bottom to provide resistance to pulling and joined to the "pull" loop at it's opposite end. When the loop is pulled it frees itself from the lead tube drawing the wire through the friction composition and the resulting flame ignites the delay pellet.



Operation: The metal cap is unscrewed from the handle and the porcelain ball is pulled. This will pull a wire through the delay pellet. The grenade is then thrown and after 4-5sec. delay the delay pellet will initiate the detonator.

second and late variety :




At the end of the war, a new model got issued which had the top all made of pressed steel.
The threads were pressed too instead of the older fine machined threads.

Safety caps


Another change in the early years of the war. The safety screw cap on the base of the stick was first issued with a spring fitted in it, for easy removal. Later types did not have this spring.
The right photo shows the newer model on the left, the older model on the right with the spring under the cardboard disc.
Caps are known in pressed zinc or pressed steel plate.

A winter-safety cap existed which made it easier to unscrew with gloves on.

Well, can anyone verify that? I got me one of these some while ago, stamped with a DRGM number stamp.
I have a feeling that it might just be a maker's interpretation.
Can anyone show some prove on special safetycaps for the winter front?




The two winter-caps below show other models. Photo thanks to eBay.
