AIRWEIGH
Компания Helix была основана в 1887 году.
Helix was established in 1887 under the name "The Universal Woodworking Company Ltd."; it manufactured wooden rulers and metal laboratory apparatus.
In 1894, it patented the drawing compass and, with it, launched the Helix brand, following on from the initial success of the compass and rule.
In 1912, the company's first mathematical set was created; and, in 1935, the brand "Helix Oxford" was launched.
1955 saw the company become known as the Helix Universal Company, and moved its headquarters to Lye, West Midlands.
In the 1960s, the name again changed to Helix International Ltd.

The base of this balance is made of casted aluminum. The balance has five weights: 4 oz. 2 oz., 1 oz. and two pieces of ½ oz.. The latter two differ in shape,
in this way it is possible to make a nice pile of weights. To check if the scale is in equilibrium, the vertical position of the pointer is a good proof.
Practically, to determine the needed value of stamps an equilibrium is not at all interesting. At the front the English inland postal rates are printed for letters,
for printed papers and for postcards. These rates were valid in the period October 1 1957 till May 17 1965. This
Letter balance was produced by Universal Woodworking Co. Ltd. from Birmingham, Engeland. Slightly different models exist also. In the book Scales a collector´s guide
by Bill & Jan Berning a silver-grey specimen is presented, it has the postal rates of 1956. Elsewhere, Helix (Universal) Co. Ltd. is mentioned as maker of the Airweigh.
