In the catalog of the perfins of the Netherlands and OR 3rd edition the perforations are displayed per perfin and per NVPH catalog number.
\nThis has not been done for the airmail stamp NVPH no. 9, although this seal is known in two different types, namely 9A in comb toothing 14\u00bc: 13\u00bc and 9B in line tooth 12\u00bd.<\/p>\n
To improve the perfin catalogue we ask you to measure the airmail stamps no. 9 you possess and report the result to Jan Verhoeven by e-mail: keurmeester@perfinclub.nl.
\nIt is not necessary to work through your entire collection, because as far as known there are only seven different perfins in these air stamps: GWC, HC 1, S 2, VD 2, VH & C 1, VH & C 2 and VN 1.
\nThe result of this inventory will be included in the next Perfinpost and shown on this website.<\/p>\n","protected":false},"excerpt":{"rendered":"
