Who recognises this Portuguese maker's mark?

[SilverNL]

Hello,

Who can help me identify this Portuguese maker's mark? I know it's a silver Portuguese ewer from Porto (first standard .916, in force from 1938). Who can tell me more about the age and maker of this beautiful large and heavy ewer?




Thanks in advance & best regards,
SilverNL
