Sorry Peteblight, it's a CRG-42, practice grenade, not a RG-42 filled with TNT !
CRG-42 contain a practice filling but I can't say what for one.

The CRG-42 (Polish) is made to receive a short 12 GA cartridge with a flash and sound composition. It is all black with a red band and white markings on the closure disc. The grenade is meant to be "reloaded" for reuse.
Your's here seems to be missing the base screw which protrudes out of the base plate section.
 
Thanks Guys,

EOD
I have the complete grenade EOD with the base screw but without the cartridge.
I also have a drawing where you can see the cartridge but it does not say what is in it.

Regards,

Chris
 
I believe it is much smaller than a 12 gauge round. It looks like it is more like a .410 gauge. It's shape reminds me of one of the "Vitamin" Pills that were used on rifle grenades for that extra UUuuuuuuummmmpphh. I have one here somewhere. I'll look for it.
 
Mark, it is a 12 GA. Chris may measure the chamber or just use a fired 12 GA case as a gauge to confirm.
 
I would like to do that but at the moment it is in stock because we are moving our unit from Culemborg in the Netherlands to Soesterberg.
Maybe next year I have the oppurtonity to do it.

Regards,


Chris
 
A 12 gauge fits perfectly in the CRG-42 adaptor (accept for it's lenght)

It is being manufactured using 12 gauge ammo components. The same cartridge (in the picture below should be rotated 180 deg:tinysmile_shy_t:) was used also in practice rifle grenade KCGN and AT practice hand grenade RPG-43.

Yu're right, during recent years I saw black ones only (acording to pre 2011 ammo marking rules, black colour with red stripe means practice item). The red one is older. Moreover I remember the case of brown cardboard colour (found about 30 years ago).

Hello Przemo,
I have an inert CRG 42 and am a little confused as to it's operation. Until I saw the picture on this thread i didn't realize that a short 12 guage cartridge fitted in the base. I had assumed that a detonator in the UZRGM fuze ignighted the smoke composition. An inert short cartridge certainly fits the base unit but what strikes the primer and why. The fuze is marked also CWCZ and has a red stripe on it. Could this be the wrong fuze, (Czech), perhaps? I'd be very grateful for any information, as I may have catalogued it incorrectly?
Many thanks,
navyman.

Hi Navyman,
Your fuze is OK - stamped "ĆWICZ" letters and red band on safety lever (later the lever was of black colour with red stripe). 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.
 
Any drawing or manual information showing the functioning of the fuze head lever section which is usually cut off etc.
 
Recently recieved a CRG-42 from fellow member & was wondering how the sound charge operated. Gonna have to soak the shell housing as the cap is seized a bit. Thanks for the great post guys!
