Can anyone help with a cartridge identification, please.

Hi, not sure if this is the correct area to ask for any information on a cartridge I have.
It is 6 3/4 inches long and approximately 1 1/4 diameter. Hope the pictures work to explain better. Thanks in advance.

Looks to be some kind of burned out flare or tear-gas round.

I'll throw in a WAG - large(artillery) primer.

I would say a primary cartridge that goes in the tail of 120mm mortar.

Yes and looks French

Thanks for your replies. Are they very common? as I cant find any pictures online, unless I'm doing it wrong.
