New Zealand 1936 5d multiple watermark – unlisted perf 13½x13
We have a block of the 5d Swordfish that appears to be an unlisted perforation gauge.
Stanley Gibbons list under SG584 in Part 1 2021 edition the following perforations:
- Perf 13-14 x 13½
- Perf 12½
- Perf 14 x 13½
This block measures perf 13½x13...
While there is a footnote after SG590 saying there are variations in these perfs within the sheet, none of these is consistent with a vertical perf of 13. Is this something new or do the perfs just vary that much on this issue? Maybe a New Zealand specialist will know the answer?
