The closest I can make out in The Illustrated Encyclopedia of Handguns by A.B Zhuk, this appears to be a Belgian 'Perfectionne;Henri Pieper & Companie (later Anciens Etablissements Pieper), Herstal-lez Liege. 8 mm Lebel; six-shot. A smaller and lighter version of...'the Pieper, or Bayard.
Though the hammer shape is different and the drawing shows only a partial-length ejector rod.
Anyway, if the right leg of the A and the left side of the [b]E]/b] are a single line and the five-pointed star is centered above them it is a Belgian inspector's mark.
