    I'm unable to tell from the photo and discription. Post for sale as Unknown Inert Fuze with a lot of close up in-focus photos.

    The 'PDF' is for point-detonating, which I remember as having a 1/20 second delay with no superquick function. I was acquainted with the PD, PDSQ, MT, and VT, but I don't remember designations MIV or MV. The fuses were identified for issue purposes by the last four digits of the FSN on their packing, such as 'N335', etc. But I can no longer say gospel, it's been too long.

    I appears to be either a Mortar(81mm) or 105mm fuze with the booster charge. Should have a lot # in it.

    When I was fooling with the stuff (back around the War of 1812), smooth-tube mortar (non-rotating) rounds were inertially-armed, with the striker interruptor lock retracted by inertia, and the interruptor itself then ejected under spring pressure from the side of the fuse when it cleared the muzzle. Fuses used in rifled weapons were usually centrifugally-armed but sometimes also used an inertial-arming system which was internally contained. The latter fuses will have no apertures. The best idea may be to have your local PD's bomb-guys look at everything, because they'll have the components in hand, and they've got the manuals.

    A funny fuse story: Once, some NG's that were in for training were firing 81's, and they had a squib with a heavy WP round. It halfway cleared the muzzle and the striker interruptor ejected itself from the fuse, like it was supposed to. Then the round slid back down the tube, armed. When I showed up, the NG Lt. had cleared the area of everybody, and when I said I would need two volunteers, the Lt. elected not to be one[:D]. I had the soldiers remove the tube from the base plate and tilt it muzzle down, and I caught the round in cupped hands. I noticed the Lt. was pale. I took the round away on the front seat of a three-quarter (well, it was the Army, and there wasn't 500 TV reporters present). But had I gotten t-boned on the way back to the ammo dump, the cops would still be trying to figure out what happened[:D][:p]

    Moran, your Lt. showed some real leadership..as usual.javascript:insertsmilie [;)] Pretty funny, but still, a serious situation.
    IF I take them to my local PD, they will confiscate them, call me a terrorist with a WMD, lock me up, take my guns and revoke my CCW. Even though they are not charged with any explosives.
    I belive there is a collector out there that needs these and I do like to get them to a new home. I've had them so long I can't remember how or where they came from...
    The pic is pretty well actual size. But, I'll take some close-ups (tomorrow..daylight)and as complete assembled units. Thanks all for responding.
