U.S. Demolition Firing Device Mk1

[juno-44]

Hi to everyone, I am new to this forum and I hope to find answers to this question. An U.S.M.C. Officer veteran of the Vietnam War gave me maybe 20 years ago this
U.S. pull/pressure fuse. I've tried for many years to find photos and informations but without result. I know what the fuse is for but would like to know if it is listed in
any training or reference manuals, could it be an experimental one. Thanking you in advance and hope to hear from one of you soon.

Regards, juno-44

The US Mark 1 Mod 1 was a standard Navy Issue Firing Device from circa WW2 on. Bureau Of Ordnance OP NO. 1362 is specific to these devices. I have observed examples with both Olive Drab and Gray Color Painted Bodies.

Stay Safe,

While I was assigned to the EODS I was tasked to teach boobytraps and some special demo to SPecWarGroup 2 (SEAL Tm 2 and UDT 21 and 22). This was in the late 70's and I litterly had a thousand of these, becasue they could be pressure, pressure relase, pull and tension release they were great for inital training. They were heavy and bulky to set up, now their big brother is the M 142 multi function firing device, does same thing but is plastic and 1/3 smaller

finally got one of these quite rare us navy mk1 mod 1 combination switches
does anyone know why the navy needed their own switch,technical manuals show that they used all the army boobytrap switches

Am I the only one who can't figure out what the mount with the ratchet is for?

Strap/wire around a tree/pole?

I think the rachet reel is for tensioning the trip wire when used in pull or tension release mode.


Hope this helps.
