    Three more, all have the small hole in one fin, plus an eg that is exactly two inches longer but is otherwise identical.
    Second pic is of a baby incendiary bomb that was, when I first saw it, complete with its tinplate fins and sliding det holder. By the time I finally liberated it, they had lost both the fins and the internal det holder. Bit uncommon, so unlikely, but does anyone have a spare set of fins, pse?DSCN0498[1].jpgDSCN0497[1].jpgDSCN0497[1].jpg

    The layout shown in the drawing posted by MINENAZ16 has similar features to the later RAF 11.5lb practice bombs - a solid nose, thin-walled back end for a pyrotechnic marker, and a simple nose-mounted striker held safe by a split pin. The structure is not really that of HE, antipersonnel, or incendiary, all of which have their own design characteristics, but it would be nice to find a drawing describing Method of Filling.


    *The markings on a relic 3lb bomb in my possession a long time ago were the year 1915 and the letters W D either side of a broad arrow. I cannot recollect any other markings.

    Tom,

    You may be amused to note the entry in the Research Department's drawing register for the drawing shown by MINENAZ16. Even scientists in Woolwich Arsenal had trouble identifying this practice munition unless of course it really was dropped by a German Airship!

    Thank you, Norman. That is excellent, especially as I have found absolutely nothing regarding contracts for practice bombs of any type.

    Considering the large objects (HE and incendiary) the Germans normally dropped, it would have been an odd device to drop from an airship. Maybe it was a pathfinder Zeppelin.



    Tom.

    Brilliant post Norman. A comfort to all of us who have mis-identifed things over the years. We are just carrying on an old tradition!

    I agree with Tom on dropping that this tiny bomb from an airship would make no sense. Even the first 'bucket' incendiary bombs they dropped were far larger.

    John,

    Searching on the RAF Museum site (finally...) shows they are aware of such a bomb, describe it as 3lb practice, and associate it with the Great War years, 1914-1918. Might be worth contacting them if you want to find out more.

    Thanks Tom

    I'm due to visit the RAF Museum in 3 weeks time so will send them a message to see what documentation they have. Especially in the light of you not finding any contracts for their supply.
    William Mills - Thank you!

    The Striker is 45mm / 1 3/4" Long. The wire at present is 1mm thick and the hole 1.5mm. I cannot guarantee the wire is original.

    Here's a photo of the bomb dismantled.
