    Mk1 A/P Training Shrapnel Mine info please

    Mk1 A/P Training Shrapnel Mine
    Does anyone have any information on the Mk1 training shrapnel mines. I was helping someone who works in clearance with some info and have found reference to them and found a photo here on bocn of a practice one but other than that nothing to say how the training/practice version worked.
    Was it just an inert version for classrooms ? Did it contain pyrotechnics emit smoke ? did it project into the air the same as the live version ?
    Any info on the training/practice version ?
    Thank you
    Allan

    The attached images are all i have found of a practice training version and were posted by member kiwieod in 2015

    Mk 1 and Mk 2 difference in the lever length and pocket depth. I believe the Mk 1 mine didn't allow enough time for it to bound high enough to be effective, hence the Mk 2 with longer lever and different det.
    Not sure of a training one, most probably the same colours as another type of practice or drill mine of the time. The only practice bounding mine the British used was the concrete MD made British training S-mine that has an igniter that gave a flash. https://www.lexpev.nl/minesandcharge...tishsmine.html my contribution to Lexes site about this mine. I think they would have trained with this to disarm such a mine. With the British shrapnel mine i think the training would be to show how it worked and the best way it was laid and and set up etc.

    Reference to a practice training mine on another thread, the practice was black with yellow band only used for mine laying.

    Mine, Shrapnel, Empty , Fuzed, Inert.

    A supply of empty bodies with all the components necessary for laying training, but with no live components were issued.

    There was no provision of Ballistite cartridges for use with this inert mine and no detonator.

    Having trained at laying the mine until bored witless in true military fashion, it was possible to use a standard.303" blank cartridge in lieu of the Ballistite cartridge, which made things more interesting, by tripping the wire. The mine went about 9" up in the air.

    Using the mine for laying training , makes it for drill purposes, but if you introduce a live component then it is being used for practice.

    I think that the above designation was carefully chosen.

    3 to 4 feet. That was the Mine Mk1 which had the Fuze Inst.
    Nothing was said for the Mk2.

    A 1940 source reveals that the desired operating height was 4 feet and that the variation would have been caused by the Fuze Instantaneous Mk4 length, however slight.
    As an aside, the permitted variation in burning time of Safety Fuze No.11 Mk 2 was 27 to 33 seconds per foot. This was further complicated by the fact that one second per foot had to be added with every 1000 feet of altitude, so chemical burning fuze times, were erratic to say the least.
    In the second plate, the cross in the circle was the monogram of the filler, the other cross was for the date of filling month and year and the triangle in a circle was the filled lot number.
    The green band denoted that the filling was Amatol 80/20. All mixtures, other than Amatol, would also have had a fraction figure above the band.
    The projecting cartridge was Cartridge .303" Ballistite H Mk 1z.
