Lintel on external skin of brick

Hi,

I have a 1950s ex-council house. The back door lintel is stone but it only seems to be supporting the inner skin (internal brick). I noticed that when the previous owners had the door changed that the bricks (3 courses above the door) had dropped down slightly. Somebody has pointed it.

I wonder whether I need to install a lintel or should the outer brickwork be supported by the stone lintel.

Cad
