Switzerland : Back Of Book.

Come on, Rod, you got that out of a bubbly gum packet!

Hi Rod,

I saw a very nice display of these G.W.R stamps in London in the spring.

They have a very interesting history.

Nigel,
would have liked to see that, information is fairly sparse on them, I think Linn's addressed them at one time.

If you do find any links, please pass them on.
(Not seen one on cover / parcel.)

Great Britain
Semi-official Airmail. GWR

Britain's Great Western Railway provided airmail service between Cardiff, Wales,
and Plymouth, England. In 1933, the British postmaster general authorized the Great
Western Railway to use a 3d grayish-green railway airmail stamp shown, for
prepayment of this service. The stamp was in use from May 15 to Sept. 30, 1933.

Great Britain's postal service stands out as one of the few long-established postal
administrations never to have issued an airmail stamp.
(Correct as to date of authorship, around 1980? since then airmail stamps have been issued SG2357a etc))

Of course, this is only true if one excludes local and semiofficial airmail stamps.
The Sanabria World Airmail Catalogue, last published complete in 1966, countries
A-M in 1972, lists no fewer than 41 semi official airmail stamps of Great Britain.
Some of these stamps are also listed in the German-language Michel catalog.
A 3d green and red Great Western Railway semiofficial airmail stamp, Sanabria S3, is
shown.

The British postmaster general authorized the use of this stamp to prepay delivery via
the Great Western Railway's airmail service between Cardiff, Wales, and Plymouth,
England, starting May 15, 1933. The service was discontinued Sept. 30, 1933.
