    Again, moderators if this is inappropriate for this forum, please move it.

    Can anyone identify this device?

    It came to me in a lot of guns, ammunition, and accessories that I bought in an estate sale several years ago. There was a great deal of military paraphernalia in the lot. It was a long time before I associated the two different pieces as belonging to each other because they were in different boxes and it was a while before I got around to reducing all of the stuff down to one small pile. Then I noticed that the threads on the cartridge portion would fit into the threaded hole in the little box.

    The cartridge portion has what appears to be a primer in the threaded end that is about 8-10 mm across. The other end is sealed with what appears to be a reddish wax substance like a blank cartridge.

    The box is about the size of a penny match box. Inside it has a spring loaded mechanism that appears to be a firing pin. When the firing pin is pulled back, a pin can be inserted through holes on corresponding sides of the box, locking the firing pin in an "armed" state. No pin was in the lot, so in the pictures, I am using a finishing nail for demonstration.

    My best guess is that it is some kind of trip wire alarm device. The "cartridge" would explode when fired by the firing pin in the triggering device when a trip wire was pulled, extracting the pin and allowing the spring loaded firing pin to strike the primer.

    There are no markings whatsoever on the device.

    I have included one pic below with a quarter for size perspective.

    What is it? Who manufactured it? Is it military or "prepper"? Anyone????

    You are correct. It is a perimeter breach detection alarm.

    Any more specific info on this particular device? I'll google the terminology you used and see if I come up with any thing.

    looks like what I saw when I googled WW2 booby trap device. I would make a point of not ever installing the cartridge to the other part until I figured out what the other part does...and im hoping for your sake it sets off smoke or something very non-destructive.

    Pen flare from a pilots survival vest. "Pen flair gun" The other part is a "mouse trap" type of booby trap. This set up would be for perimeter security for alert, non lethal. Military for sure. Never seen any maker information even when the traps were new in a card board box. Late WW2

    :) Westkentucky, I have no desire to loose any part of my anatomy, particularly accidentally. Did that 2 years ago when my left thumb encountered an angry table saw. It ain't fun. At least, two years ago, a miracle working surgeon put my thumb back on... with explosives I'm afraid I might not be so lucky. In other words - I ain't putting nothing together that might go boom unless I know perzactly what I'm doing.

    WestKentucky, I found this exact device when I googled "ww2 booby trap". It is listed as an M5 Booby Trap. The cartridge shown with the device is slightly different than mine, but I found a very similar cartridge further down in the listing without the trigger. It was also shown as a triggering device for a grenade.

    Further googling the M5 description, I found one for sale without a cartridge for $33 on a site called inertorg.com.

    In all of the pen flair guns I found, the cartridges did not have threads.

    Very interesting gentlemen, (and ladies if any are reading this). I've been trying to figure this bird out for several years. Thanks all for the responses.

    Myself I have two sets of the pen flares, but never used them although I have a pilot friend who has. Myself I carry the MK 13 Mod 0 day night flare when I want to be seen.

    I don't think the cartridge thing goes with the M5, even though the threads may be the same size.

    I think the cartridge is a signal flare, and the M5 is what you think it is.

    But it wouldn't have used a cartridge like that.

    It would have used a small detonator that threaded into it on one end and into a pineapple grenade, etc. on the other end.

    If you find one of those, throw it in a deep lake without dropping it on the way there!!

    Here are some more related things you probably don't see every day anymore.

    Original Vietnam era trip wire spool.
    M57 Claymore mine piezoelectric firing device.
    M60 Blasting fuze igniter.

    :D

    PS: Yes, none of this is reloading related.
    But I hope the mods allow it for everyone's enlightenment of things you might find in a garage or estate sale that 'can' still be loaded & dangerous to play around with!!

    This mini flare gun came with different colored flares to drop into the barrel. The flares are powered by shotgun primers and you can see mine has a loaded primer. The barrel screws off to load the primer.

    When I picked this up it had one flare with it yet but that was lost in moving.

    PS: it has no markings

    Booby trap device....not a pen-gun flare launcher. :rofl:

    M5 Pressure-Release Firing Device. Non-electric blasting cap would
    be threaded into side, to initiate det cord, C4, grenade, etc. "As lethal
    as you'd want it to be."
