Bletchley Park Post Office issues collectors' item postage stamp and cover

To mark the opening of the new Tunny Gallery at The National Museum of Computing, Bletchley Park Post Office has issued a commemorative postage stamp. The collectable stamp is available on a commemorative cover featuring 1940s photographs of the original Tunny machines, a map of World War II German “Fish” communications network, a Lorenz SZ42 encipher machine and explanatory text.

The stamp bears a Bletchley Park postmark for 26 May 2011 when the new Tunny Gallery opened in the presence of four surviving veterans associated with the Tunny machine. Amongst them was Gil Hayward who helped build the first Tunny machine. Each veteran was presented with a limited edition cover.

The Tunny machine was vital in World War II code breaking and was a British re-engineering of the Lorenz SZ42 cipher machine used in radio teleprinter communications amongst German High Command. It produced the final decrypts and provided key intelligence for D-day, Kursk and in ousting the Axis forces from Italy and France. The rebuilt Tunny machine is now on display in the museum.

The National Museum of Computing commissioned the limited edition of 250 covers as a tribute to the war-time code breakers. The issue price is £12.50 each and is sure to be sought after as collectors’ items.

Complete sheets of 20 stamps featuring the rebuilt Tunny machine are also available at £40 in a limited edition of 50. The issue will contribute to the Museum’s fund raising drive

The stamps and covers are available, while stocks last, from The National Museum of Computing and Bletchley Park Post Office. They can be viewed at www.bletchleycovers.com.

About Bletchley Park Post Office

Bletchley Park Post Office is a re-creation of the original 1940’s sub post office attached to the Bletchley Park Mansion. During World War II, the building served as a mailroom for the 12,000 people involved in top-secret code breaking operations. Today, Bletchley Park Post Office is a respected publisher of limited edition first day covers. These covers are very collectable and some fetch hundreds of pounds sterling at auction. The income helps support the preservation of Bletchley Park.

About The National Museum of Computing

The National Museum of Computing at Bletchley Park, an independent charity, houses the largest collection of functional historic computers in Europe, including a rebuilt Colossus, the world’s first electronic programmable computer.

The Museum complements the Bletchley Park Trust’s story of code breaking up to the Colossus and allows visitors to follow the development of computing from the ultra-secret pioneering efforts of the 1940s through the mainframes of the 1960s and 1970s, and the rise of personal computing in the 1980s. New working exhibits are regularly unveiled and the public can already view a rebuilt and fully operational Colossus, the TunnyGallery, the restoration of the Harwell / WITCH computer, and an ICL 2966, one of the workhorse mainframes computers of the 1980s, many of the earliest desktops of the 1980s and 1990s, plus the NPL Technology of the Internet Gallery. In June 2010 TNMOC hosted Britain’s first-ever Vintage Computer Festival.

Funders of the Museum include Bletchley Park Capital Partners, CreateOnline, Ceravision, InsightSoftware.com, PGP Corporation, IBM, NPL, HP Labs, BCS, Black Marble, and the School of Computer Science at the University of Hertfordshire.

The Museum is currently open on Thursdays and Saturdays from 1pm, and on Bank Holidays in spring and summer. Guided tours are also available at 2.30pm on Tuesdays, Sundays and some other days. Groups may visit at other times by arrangement and special organisation Away-Days can be booked.
