The 1E4 5c Moreno 'Servicio Oficial'

This printing is the most common one of the five 'Servicio Oficial' issues of this stamp. The 1E4 paper is cloth-like and white. These stamps have small perforations.



This specimen, which resembles the discolored NGR printing, has a deformed O of 'SERVICIO.'







This reddish brown specimen has a second shadow overprint.





Here is a dated specimen from 1944.



I am not familiar with the use of this marking.
