SG 59/ACSC B16B: KGV
1½d Single Wmk cover black on pink with stamps being Single wmk., 1½d red brown. ACSC states this booklet has not been seen in recent times. This appears to be incorrect as we know of one other, plus this exploded booklet. Interestingly the spacing between staple holes from this period is 17mm. In this instance it is 12mm and this spacing matches the exploded panes and interweaving. A rare opportunity.
