Background: *The National Geographic Society was formed and incorporated in Washington, D.C., USA, in January 1888, as a club for an elite group of 33 academics and wealthy patrons interested in travel.

The National Geographic Society's initial mission was "to increase and diffuse geographic knowledge” but later it was expanded to include, “while promoting the conservation of the world's cultural, historical, and natural resources.” The Society is governed by a Board of Trustees whose 22 members include distinguished educators, business executives, former government officials, and conservationists.

The Society sponsors and funds scientific research and exploration and publishes an official journal, the “National Geographic Magazine” in 34 languages. They also publish other magazines, books, school products, maps, other publications, and web and film products in numerous languages and countries. Its educational foundation gives grants to education organizations and individuals to improve geography education. As of 2013 the Society’s various media activities reach about 360 million people monthly.

Device: The NGS device was a multi die device of at least 6 dies, and these are most commonly found in a horizontal array. As you can see from the image there are strikes of 2 dies in the wide format Customs Duty stamp. The dies appear to differ slightly but have a common style with a diagonal layout.

The NGS patterns are proved to the “National Geographic Society” and the various NGS's listed in the US Perfin Catalogue overlap which supports the case for a multi die device of similar dies. This is also supported by the fact that the usage dates seem to overlap.Multi Die

N.R/Co..a

User:  National Radiator Co

Radiators

Address: 439-441 Oxford St, London, UK

             2 National Ave, Hull, Yorkshire, UK

Revenue Use: 1912 issue ½d

Rarity Scale: ½d R4

 

Background: *The American Radiator company was formed in 1894 from a conglomerate of American manufacturers of sectional cast iron heaters and boilers. They marketed their product under the name “Ideal Boilers”, amongst other brand names.

In 1904, they established themselves in Europe trading as, The National Radiator Company, and they constructed a huge factory in Hull, Yorkshire to service the UK market.

Device: A single die device as the strikes are found as single and central strikes in the larger format Customs Duty stamps. If it was a multi die device made for the contemporary GB postage stamps then evidence of the strikes of other dies would be present on these larger format stamps.

This pattern is listed in “The New Illustrated Catalogue of GB Perfins” in the N section as 2767.01. This catalogue states the devices usage to be between 1905 and 1923.

Related Patterns: NR/Co.b

N.R/Co..b

User:  National Radiator Co (Unconfirmed)

Radiators

Address: 439-441 Oxford St, London, UK

Revenue Use:

1911 issue (rouletted) 4d, 5d

1912 issue 5d

Rarity Scale:

 

1911 issue (rouletted) 4d R4, 5d R4

 

1912 issue 5d R4

 

Background: See NR/Co.a

Device: A single die device as the strikes are found as single and central strikes in the larger format Customs Duty stamps. If it was a multi die device made for the contemporary GB postage stamps then evidence of the strikes of other dies would be present on these larger format stamps.

This pattern is listed in “The New Illustrated Catalogue of GB Perfins” in the N section as 2775.01 and a stated usage period of 1910 until 1930.

The user of the device is unconfirmed in the GB Catalogue but given the similarity in the patterns, and the usage periods, it is reasonable to assume that they are the same user. The evidence provided from the use of the two devices/patterns on Customs Duty stamps is circumstantial, but still strong.

Given that there are about 25,000 known patterns in the GB Catalogue and only a handful of these perfin users applied perfins to Custom Duty stamps, it would be most unlikely if two of these users of perfins on Customs Duty stamps, had the same letter combination, almost identical patterns, the same device layout and complimentary usage periods and yet were different users.

Therefore it is most likely that the NR/&Co.b device was used by the National Radiator Company.
