French patent agent Blétry frères was recorded as being at address boul. de Strasbourg, 2, Paris[1]. This fraternal collaboration may have been a gradually formalized development. It would seem to refer to C. Blétry and E. Blétry prior to their father's death in 1901. See Blétry for what clarification we have at present. See also Blétry aîné.
