The Simplex Wire & Cable Company had its beginnings in 1865 with the formation of a partnership between Charles A. Morss, who had his own wire making firm in Boston, and Oliver Whyte, to manufacture wire products. They made their first insulated wire in 1885 as an experiment. Following a fire in 1888 the company moved to new premises in Cambridge, Mass. In 1890 Morss and Whyte took over the Simplex Electric Company who had been acting as selling agents for them. They merged the two firms in 1895 under the Simplex name. This company was to concentrate on the manufacture of insulated wire and cable. One of the first submarine cables they made was a five mile telephone cable which was laid across the Straits of Mackinac in Lake Michigan; another, this time one mile in length, was laid across Boston Harbour. Both were laid in 1900. Problems in obtaining gutta percha for insulation forced the company to use rubber insulation, which only lasted for a few years due to proteins in the rubber absorbing moisture. To get over this they used lead sheathing on some cables. By 1926 they had developed a protein free rubber which they used for power and telephone cables. The first submarine cable using the new product was made in 1933 for the US Coast Guard and laid between Florida and the Fowey Rocks Light. The success of this cable led to many similar contracts. During World War II they produced over 3000 miles of cable for the US Army Signals Corps Alaskan Communication System as well as cable for harbour and coastal defence work. Bell Telephone Laboratories restarted their research on telephone cables after the end of World War II and Simplex was invited to join in on cable and repeater housing development. In 1948 Simplex manufactured 20 nm of coaxial cable which with six repeaters was laid by CS Lord Kelvin in the Bahamas. The first commercial system using the new cable was laid between Key West and Havana in 1950 using twin "go" and "return" cables. Twin cables were also used on the Atlantic Missile Range System installed in 1953 by HMTS Monarch (4); repeaters for this cable were installed on land. On the 26th November 1953 the company opened a new factory on the banks of the Piscataqua River at Newington, New Hampshire solely for the manufacture of cables, both power and telephone.

About Specimen Certificates Specimen Certificates are actual certificates that have never been issued. They were usually kept by the printers in their permanent archives as their only example of a particular certificate. Sometimes you will see a hand stamp on the certificate that says "Do not remove from file". Specimens were also used to show prospective clients different types of certificate designs that were available. Specimen certificates are usually much scarcer than issued certificates. In fact, many times they are the only way to get a certificate for a particular company because the issued certificates were redeemed and destroyed. In a few instances, Specimen certificates were made for a company but were never used because a different design was chosen by the company. These certificates are normally stamped "Specimen" or they have small holes spelling the word specimen. Most of the time they don't have a serial number, or they have a serial number of 00000. This is an exciting sector of the hobby that has grown in popularity over the past several years.
