Greener Police Shotgun from Hong Kong

[Dreadnought1]

Hi folks,
I posted this in the Martini Henry page of the forum but no joy there as yet so I thought I'd drop it in here too.

Does anyone know what round the Hong Kong Greener police shotguns were chambered for?

I know the Egyptian Police used a special catridge but I can't find anything online as to what the Hong Kong police used.

I've been offered one and haven't handled it yet but I've been told that the receiver is marked "Greener Mark II" and "HKP 6xx" and is also marked with a .719" , a 12 in a diamond, 2 7/8" and 4 1/4 tons (PSI).

I'm hoping it'll take standard 2 3/4" 12ga rounds (because I don't want the hassle of having special rounds for it).



Thanks in advance for any info.
Cheers,
Dreadnought1

12 in a diamond indicates proofing for 12ga. Chamber length is 2 7/8 is longer than 2 3/4 shell length. You should be good to go.
