FIELD TELEPHONE

Obviously a field telephone but other than that nothing is known. Judging by the materials used it looks very old possibly pre WW1, the transmitter looks like a Deckert type as shown in GPO training manuals (Telephony Vol 1 Herbert & Procter Page 227) and does not turn as suggested in the comments section. Any more information would be appreciated.

L.M.ERICSSON GPO TELEPHONE No.16, circa 1909

This instrument was designated the No.16 by the British Post Office and was in use until the 1950's. It is based on an earlier design introduced in 1895 which looked almost identical and was supplied to the National Telephone Company.

The example shown was made for the GPO by L.M.Ericsson and is is marked No.16. The transfers are almost certainly not original.

INTERNAL TELEPHONE, 1920's

A small wooden telephone used in offices or coal mines for one to one communication. Two units and a small battery is all that is required to work these units. Working with this instrument in coal mines could be a problem if there was gas around, never the less such units were seen in mines in the early days of Telephones. Strict rules would apply to their use but communication was as important as safety and the position of the instrument was carefully considered.

Known as a 'Direct Line Wall Telephone Set'

The type 2000 Strowger selector is part of a 'Final' type selector, although many types of Selector are used together to establish a final connection, each one having a specific task. The way the call is finally connected is to complicated to explain here. This unit is used in the museum to demonstrate the Strowger principal. Almon Brown Strowger conceived his idea in 1888 and obtained a Patent in 1891. He was an Undertaker whose business was being deprived of customers due to a manual operator lessening in to his calls. She being the wife of a competitor whose husband was stealing his work, Strowger was so upset by this he decided to find a way of eliminating the position of manual switchboard operator.

NYLON COATED TELEPHONE CABLE, 1960's

Data cable with armour protection, coated in hemp which has been saturated with a mixture for under ground use.
The Transcontinental Cable System or L-carrier system, was developed by AT&T to create a hardened Telecom network using coaxial cable for long distance communications. There were five phases of development of the system, designated by the Bell System as L-1 through L-5. Later versions were hardened against the dangers of the cold war.

The initial systems in the 1930s had 600 voice channels, far more than could be carried by balanced pair carrier systems, and cheaper per channel for high-usage routes. This version was standardized as "L-1" in 1941. Each successive version had at least twice as many channels as the previous version, culminating in the L5 design in the 1970s, which used the then-novel error-control method of feed-forward. AT&T Long Lines built two coast to coast systems of L3 as well as shorter ones connecting major cities, especially the big cities of the eastern United States, as a supplement to the mainstay microwave radio relay systems. Many were later upgraded to L4. L-carrier systems were loaded by multiplexing and super multiplexing Single side-band channels.

MOTOROLA DYNA TAC MOBILE PHONE 8000S, 1986

The Worlds first hand-held mobile phone was demonstrated by Martin Cooper of Motorola in New York City on 3 April 1973, using a handset weighing 2 kilograms (4.4 lbs), and named the Dyna Tac. However launching it as a viable commercial enterprise had to wait until sufficient Cellular send and receive masts had been installed.
The world's first commercially available mobile phone was the Motorola Dyna TAC 8000x. It went on sale in 1983 in the US at the staggering price of $3995, and despite the price tag, was an instant success and had waiting lists of up to six months! It went on sale in the UK on 1st January 1985 and the very first phone call was made by Ernie Wise! It was followed in the UK in 1986 by the 8000s & in 1988 by the 8500x and in the US in 1990 by the 8000m. These phones are all analogue.

MOTOROLA 8800X MOBILE PHONE, 1990

The 8800x, 8900x & 888 were the new generation of the brick phones as they were slimmer than the previous 8000 and 8500 series models. They were just as high and wide, but a whole 2cm less deep! The 8800x and 8900x were made from 1990 to 1994 and were designed for the UK market. In the US they were branded as Classic and Ultra Classic. Some have an LED (Light Emitting Diode) display and some have a modern LCD (Liquid Crystal Display) display that we still use today. Some had a large LED display and some early ones had the smaller rarer LED display. The ones with the small LED's are the most collectible. All these phones are analogue.

A1343

MOTOROLA MICRO TAC 9800X FLIP TOP MOBILE PHONE, 1991

The worlds first flip phone was the Motorola Micro TAC 9800X launched in 1989. It's a design that is still seen today on millions of mobile phones around the world. The phones and batteries may have got smaller and more powerful, but the basic design is still there. The early phones were all analogue, and had the small LED display that is sought after by collectors. The later phones had the modern LCD display and some of them were digital and can still be used today. One of the best features of these phones is the antenna, which pulls up from the top of the phone. The antenna is just a piece of plastic and has no affect on reception. The phones antenna is internal, but it was felt that customers would want to see an external antenna, so one was added! On the 9800X the microphone was built into the flip part of the phone, but on all other models, it was in the body of the phone and the grooves cut into the flip are just for show. The basic design was used in many different types of phones, branded with many different names. Some of those phones didn't have the flip, some did.

The Manufacturer E.M.T. is a mystery, it is a possibility that it could be EMI who made it, the last letter 'T' being a code, as in War time Utility sets, that used a letter codes to indicate the maker. Off course as this is a Secrecy set it would not be good practice to divulge the maker.
