Russian training mine OZM-3 information

[BMG50]

Had a look at a Russian training mine today I believe called a OZM-3 that's what it looked like. It had a funny paddle screw key in the middle and was told that it contained a 9volt battery, that either set of a small signal maroon or a buzzer. Any one know anything about it.

Found another Training OZM-3 or O3M-3 mine, this one is a solid block of steel, weighs a ton. The igniter and electric socket are drilled our shallow to a blank and the centre det hole is bored to near the base. The igniter det cap is made of a hard plastic to stop the pin from being damaged. There is also a dummy detonator made of solid aluminium. The base plug that would hold the bounding charge by a ring screw is solid and machined out. The central plug or cap either screwed in of a push fit. It's faintly marked up with O3M-3 22, missing its cap cover and chain for the igniter cap, missing the igniter pins and wire. Not sure if they made such training versions but I can't find reference to this one.

Here are some other pictures that may relate to the mine. The first picture is one that activates a buzzer the other photo the mine on the left has the same markings as my mine. The last three letters on the bottom line are marked 8-22, in the picture it's 6-22 not sure of the obscure lettering that the photo hides.

Anyone have a good photo of the shipping cap or know the guy who was at the W&P show one year a few years ago selling yugo mines and other eastern block ordnance.
