Blacksmith's Bellows
In the Middle Ages double-acting bellows was introduced. It had 2 parts, one operated by hand or foot, the other took air from it and was weighted so it forced air out while the part was filling. Blacksmithing is the shaping of hot iron and steel, usually by hammering. Very hot fires were produced by 1.a hot air blast. 2. burning charcoal (not wood). Bellows were used to make tools, fix equipment including machinery, drays, carriages, harnesses etc. Farmers in the Kiewa Valley often had their blacksmith forge. They made their own tools, were able to mend equipment, drays etc., gates, and most items that were made of iron and steel.Large Double Acting bellow with wooden top and bottom, shaped like a 'water drop' - narrow at one end and broad at the other. The wood is held by strips of wood and leather bound and placed around the perimeter. The wood on the top side has inscriptions (illegible). The wood on the bottom side has a rectangular hole. The narrow end feeds into a pipe to enable the fire to receive a hot blast of air. When the bellow is squeezed it allows both pieces of wood to be pushed together.Illegibleblackmiths, bellows, double acting bellow -

Helibox, Cardboard food delivery box, Early 1960s
... dropped from the air. Wings held in place by means of string... dropped from the air. Wings held in place by means of string ...The successful dropping of supplies to remote fire crews involved a great deal of experimentation. The result was a large heavy-duty cardboard container being developed in 1964 by Athol Hodgson from the FCV Fire Research Branch which employed fold-out wings and was called the “helibox”. It was suitable for supplies weighing less than 9 kg and best dropped from about 300 feet and became a standard technique. It was adopted Australia wide, but the wider availability of helicopters made the helibox eventually redundant. Unique to Victoria but adopted across Australia.Large cardboard box with "wings" to cause it to rotate when dropped from the air.

Drop Chute
From the early 1960s, the Forests Commission had pre-season arrangements in place with local aeroclubs and pilots across regional Victoria. Air observers from FCV districts routinely flew during the summer months in small, fixed-wing aircraft on fire spotting missions and to map fire boundaries. The information was often needed quickly by crews on the ground or in the control centre and these small chutes were used to drop messages and maps from the reconnaissance aircraft on a low pass above a cleared area like a football field. About 3-foot long when fully extended, they had a small pouch secured with a press stud for the map or package. The chutes were made from tough canvas with a small, weighted sandbag at one end and a long yellow streamer tail on the other to help direct its fall and locating it on the ground. Drop chutes were still in common use in the 1990s, but the increased availability of helicopters combined with improved digital data transfer made drop chutes redundant. Simple, but now redundant technologyAerial drop chute"Return to Forests Comm Vic" stenciled on sidebushfire -
