Mod.42 polish smoke or blank firing training grenade

[BMG50]

I am trying to find out more info on this type of grenade CRG type. The bottom appears to screw out revealing a reloadable base with vented holes and a hole for a cartridge to fit. Was this grenade a reloadable blank firing grenade or a smoke grenade, what type of cartridge did it use, looks like an interesting bit of kit.

The CRG-42 is using a special (and shortened) 12 GA blank cartridge. Unfortunately I can not say how they arranged for the delay.

The following text is from post no18 in this earlier topic http://www.bocn.co.uk/vbforum/threads/81679-CRG-42-Hand-Grenade/page2

"The fuze's delay element is ended with small black powder charge and closed by metal cup (usually this part is not preserved). The cup has small protruding on its base which acts as a firing pin to strike the prcussion cup of flash-smoke cartridge."

I did try to look for a thread on this topic but did not look hard enough, sorry about repeating the topic.

I get a clear picture to how the cartridge is positioned but does the cartridge have a delay in it or is the leader striker made to have a delay?

The delay is in the fuze just. As you can see in the picture it is a 3 seconds delay. The 1st picture it is in normal position; the 2nd after fire with the hammer out; the 3rd is the hammer pin who strikes the cartridge cap.

 

[BMG50]

So the pin is pulled the lever flys off the striker, sets of a cap that has a 3 second delay, which then sets off a charge that forces the hammer striker to hit down on to the primer of the shotgun cartridge, setting that off.
