    British bomb detonator ID

    Hello,

    We found a British 500lb (ww2) fuzed with a Pistol 30 mkIV with a detonator unknown for us.
    We usually find detonator with green paint on the bottom.
    I know the black circle is for the delay (detonator N°51) but what is the difference between green and black paint on the bottom ?

    Regards.

    Hello,

    I think it is the difference between Anvil type detonators and Sensitive detonators. The first type are identified by a colored band of 3/8" wide around the detonator head. The second type are identified by the stem, which is painted green for a length of approx. 1" (2.54 cm) from the closed end and by a green label inside the detonator head.

    Rgds,

    I agree Mossie.
    From the book of David Andrews and Alan Swan, "British bomb and rocket pistols and fuzes", the green band on the stem will identify a sensitive detonator.

    You can find the same text on this book, pg 315.

    Hello,

    Thanks guys.
    Yes I know green stem meens a sensitive detonator but I have no reference on black stem. As far as I know Pistol No30 with his long striker was used with a sensitive detonator.
    What is the difference with Anvil detonator ?

    Do you need the differences between sensitive and anvil ?

    Minenaz16,

    I can't find any reference in A.P. 1661C to black stems, is it possible that it is green paint that has become discoloured?

    Thank you TimG.
    Yes maybe a change of color with time and moisture.

    Yoda, sorry, I know the difference of construction between anvil and sensitive but I don't know if stems of anvil are painted.

    OK, if I follow another source (H.Belot), only the sensitive detonators had a green band on the stem. In his Deminest, he let see a drawing of a detonator with the green stem and a black head collar.
    Now, for me, I have two solutions on your problem :
    - as writed before, it could be a passed green color wich became black
    - british manufacturors repeated, for X lots of detonators (it's not frequently !), the head band color on the stem (to verify).

    If it is always possible, a X-Ray view of the detonator should let see if it is an anvil detonator or a sensitive detonator !

    One would have to have a photo of the 2 detonators to more accurately see the colors. I am also of the opinion that the color has changed over time into a black green. The detonator was about 70 years in a bomb installed in which chemical processes have played. Gruß an alle!!!! Harry
