British Machine Gun?

Hi everybody
I am residing in Sweden. I have in my possesion 2 machine guns.
My father ones told me they are from a British Aircraft, crashed in Norway.
They have following data: 303 MK II B Y 93720 B and written with yellow paint LJ 899 D4

Is it possible to identify them?

Best regards
Per
