Identifying 4.7" shell markings

New to the forum, looking for help identifying markings on a British 4.7" shell, specifically the manufacturer / arsenal marking (a thistle?). Any help would be appreciated!

You could also try the British ordnance forum website: bocn.co.uk

GreameD, thanks,will give it a try when my IT guy (son) is available for helping post stuff.

Do you have any more photos of the shell?

As a newby we were only allowed one pic apparently…the shell is ‘fired’ but in quite decent shape and came with a type 65a fuze which i doubt was attached to it when fired.
