THIRD WATERMARK: £1 grey Type B BW #53x from the upper-right of the pane with top & right-hand marginal watermark lines, very well centred, rough perforations cleaned-out, unmounted, Cat $6000. Advertised retail POR. Surely one of the finest examples extant. [This is a notoriously difficult stamp to obtain well centred. Vastly superior to the ugly unmounted example that sold for $3910 at a Melbourne auction in August 2011]
