Thread: Help identifying the maker of a rifle

Been down to Wellington with a mate to the antique arms auction
And I picked up a very nice piece of wood and steel
What i do know is it’s a martini express rifle in 450 no1 express

In good shootable condition with a nice bore for age
But sadly externally its been rusty at some point
And the ingraveing is obscured by light pitting
I can make out the serial which is nice considering

And I can make out “martini patient”
But the actual makers names and crest are obscured

I can make out (quite large on the frame ) 2 crossed flags inside a circle

Any ideas what it is
