Little sterling 925 cross - hallmarks

[Flanders]

This little cross comes from Romania. Can't seem to get a really good picture of the mark because it is so small.

Period?
It is 925 for sure. I can see that 'clearly' with a loupe. The rest? Can't be sure, too blurry.

03? 33?
NU, MU or HU?
925

Any information is welcome. Thanks.
