The Bruck Inhaler is a modification of the Clover Inhaler, designed by Lambert Bruck. Bruck added a glass dome which enabled the level of ether to be monitored during administration. This was a revolutionary change as it removed guess work from the process.The inhaler is oval shaped with two halves. One half should be made of glass [missing] to allow observation of the ether level. A vertical cross tube, 22mm in diameter passes between the face-piece and the bag [broken]. There is a stopcock for admission of oxygen or nitrous oxide opposite the bag attachment. There is a central tube, 28mm in diameter, with controllable ports on either side.The Bruck Inhaler is a modification of the Clover Inhaler, designed by Ludwig Bruck.

The Canadians developed a machine that used "ping pong balls" instead of cylindrical incendiary capsules and, in 1977, the FCV purchased a Premo machine for evaluation. The 32mm-diameter balls were made from high impact polystyrene and contained 3.5g of potassium permanganate. They were injected with 1ml of glycol which would ignite after a short delay The first Premo machine used four slipper blocks, which were loaded via a hand-operated hopper which, when rotated forward, the balls would be fed into four feed chutes to individual slipper blocks. Each slipper block has an opening allowing individual balls to enter and exit once injected. The original design of the machine was not suitable to meet the burning objectives and a number of modification were necessary. Following close inspection and field testing it was clear that utilising four slipper blocks was excessive and would generate too much fire. It was acknowledged that satisfactory spacing could be achieved by using just one slipper block. Selective spacing could be achieved by the speeding up or slowing down of the slipper block transferring the capsules during the injection process. Regulating the speed that the injected capsules were being dropped controlled the amount of fire created on the ground. This machine was the result of many years of experimentation at AltonaSignificant development of aerial incendiary machines enabled expansion of the fuel reduction burning program across Victoria.Aerial Incendiary machine for use in helicopters Modification at the Altona workshops over many years by Barry Marsden forests commission victoria (fcv), planned burning, bushfire, bushfire aviation

Handwritten sketches showing additions to the Police/Emergency services communications tower in 2004. Harry Gilham noted that the cylindrical shaped object was blocking the view from the War Memorial tower to the land area and made suggestions to the Nillumbik Shire Council and CFA that it be raised to the sky area above the Mt St Leonard-Healesville range.Colour photo print 12.5 x 19 cmHandwritten notes on both sides regarding 2004 modificationskangaroo ground, shire of eltham memorial park, emergency services communications tower, harry gilham, nillumbik shire council, war memorial tower
