Help identify this hh

[Scubadoo]

Hi ,new to the site , was looking for some help identifying what looks like a percussion primmer . I found it while diving in Milford Haven on a wreck called "The Collier" It has several markings on the base " GK and VII " also what looks like the letters "L&M" in a kind of script font . The screw-on brass bit has a shield with what looks like E6 and Co. stamped in the middle,and a letter I. Any help much apprieciated.

primer

Hi there,what you have there is an adapter mkVI with a metal igniter. It was a 'protruding' primer that was used on 12pdr 12cwt cases and some 4.7inch cases too.Ben

i'm afraid i'm not really up to speed with all the different makers. Hopefully someone else on here can let you know the makers.

Here is a link to one i posted on here recently: http://www.bocn.co.uk/vbforum/threads/80187-12-Pounder-primer-sold-on-ebay?highlight=12pdr
