NSW Postage Due Perforation question
I've attached a page from ACSC Postage Due catalogue describing the differnent perforation options. I have also attached a PDF of EzPerf, a digital perf gauge I use which gives me much better (and demonstrable) accuracy on perforations. As you can see the perfs are 11.25 x average 11.55. What are your thoughts as to what this stamp is (catalogue number)?
