    L1A4 Vent tube

    I have a vent tube in the style of the Challenger tank vent tube, but it is dated 1979, which is too early for the Challenger. Which gun system used this?

    I posted this in projectiles because I didn't really know where else to put it.

    The headstamp is: RG PZ 79 L1A4

    This tube's dimesnsions, case material (brass) and primer are all identical to the one used in the gun on the challenger, it is only the date that is a bit early.

    Pre production ?

    Interesting Falcon as it is an early date as you say !

    The only thing I could think of was that it might be an early pre-production item but then it would have either had no headstamp or an experimental one ie XL1E4 or similar ?
    Cannot think of any other weapon of the era that used this vent tube.

    Thanks for the reply.

    Thanks Spotter.

    Does anyone have any idea what the "PZ" on mine stands for?

    Isn't there also a larger one of these for use with an earlier gun system?

    Thumbs up Electric ?

    Falcon
    May be a silly question but, your version is an electric contact firing circuit round ?
    PZ may be "Piezo" which is why I ask if it is electrically initiated the same as the standard cases ?

    I also wondered if "PZ" was "peizo", but then remembered I had seen other letters.

    Interesting photo of the magazine weasel.

    Does anyone have any idea how these look when they are live, can anyone post a cutaway drawing of one?

    Also, could anyone post a photo of the breech block on the Challenger gun where the device that fires these will be?
