Woodwork, Wood plane, Early 20th century
This hand tool would have been used either in the home for making small items of furniture or small building projects or it could have been used by a tradesman working on small jobs in the building industry – window sills, doors, cupboards etc. Planes are still used today to whittle down wood. This tool has no known local provenance but it is a good example of hand tools of the past and will be useful for display. This is a metal plane used for shaving wood. It has a rectangular base curved at the ends and the end of a steel blade is visible near one end of the base. The handle is dome-shaped and attached to the handle by a screw is a ridged metal wheel that rests on the blade which has been inserted on an angle. This wheel can be turned to adjust the blade, keep it in place or remove it for replacement. The plane is much rusted (it may have been painted black) and no manufacturer’s marks are visiblhousehold tools, wood plane -

CALAID V - Hearing Aid, National Acoustic Laboratories, Early 1980s
The first all transistor hearing aids appeared in 1953. They were created to replace vacuum tubes; they were small, required less battery power and had less distortion and heat than their predecessor. The vacuum tubes were typically hot and fragile, so the transistor was the ideal replacement. The size of these transistors led to developments in miniature, carbon microphones. These microphones could be mounted on various items. There were body hearing aids where the earpiece was connected to the hearing aid and battery pack worn on the body. Ear level hearing aids consisted of eyeglass, behind the ear (BTE), in the ear (ITE), and in the canal (ITC, CIC) hearing aids. A new aid type, the Calaid V, was introduced featuring a forward facing microphone, and three potentiometers for adjustment of maximum gain, maximum power output, and low frequency roll off. The Calaid V was introduced in the early 1980s and remained the most frequently used aid in NAL's service for the next ten years (From: THE CALAID: AUSTRALIA'S OWN HEARING AID by Laurie Upfold and Ray Piesse Single Behind-the-ear hearing aid.
