These stamps were usually initialled by the postmaster, or the Post Office clerks, before they were issued. The initials are-E. T. E. D(alton), E. D. W(ight), J. B. S(mith), H. A. K(illikelly), and W. H. L(ortimer). There are several types of each value and it has been suggested that the setting contained one horizontal row of four slightly different impressions.
