1/- lyre, perf 13½ x 14. A positional strip of 4 showing perf. guide mark in selvedge at right (SHEET A). These markings are the impressions from the striker plates of the mechanical punching device introduced for better perforation centring. It certainly worked in this instance. All stamps are fresh and mint unhinged and well centred. Light hinge remainder in upper selvedge only. Very scarce in a corner strip of 4.
