MOBA2 is a 15 metre sailplane designed by Gary Sunderland, who was an aeronautical engineer working for the Department of Civil Aviation (Australia) and a member of the Victorian Motorless Flight Group (VMFG). The design gave effect to ideas that he developed circa 1970 for an aircraft that he could build himself. He entered a 13 metre wingspan version of his MOBA design (MOBA2B) in an Australian Gliding sailplane design competition that was announced in 1970. The competition called for sailplane designs with a maximum wingspan of 13 metres that could be built by amateurs in a small workshop with limited tools and facilities. In 1973, Gary’s MOBA was judged by the competition panel as equal best with the other outstanding submission, which were chosen from a field of 19 entrants. However, after gathering further information and deliberation by the competition panel neither of the two outstanding designs were chosen as the winner. Notwithstanding the outcome, in 1974 Gary proceeded built his glider to the original 15 metre design. The wing was equipped with camber changing flaps that were permitted under special standard class rules for the 1974 world championships. Changes were made along the way in the light of construction experience and the completed glider was given the designation MOBA2C. The glider first flew on 12 December 1979. It was never flown in standard class competition as by the time the glider was built the special 1974 rules were revoked and wing flaps were no longer permitted in that class. However, Gary flew MOBA2C in the Australian national gliding competitions held at Benalla in the summer of 1979 / 1980 competing in the open class. After adjustment to the aileron gearing during initial trials MOBA2C was found to fly well and in competition produced performances believed to be better than contemporary standard class sailplanes but not as good as the open class machines. The glider was later modified in a number of respects including amongst other things the installation of spoilers located just forward of the wing flaps and by increasing the chord marginally at the wing root. With these changes the glider type was given the designation MOBA2D. The last recorded flights occurred in February 1996 at which time MOBA2 had flown an aggregate of 401 hours and 59 minutes during its 297 launches. Its operational life was brought to an end due to expansion of the foam in the wings causing distortion of the wing surface.The MOBA2 is a notable home built 1970s sailplane design that featured a number of innovative elements including composite construction without the need for expensive jigs, nose cone canopy and asymmetrical placement of control column.Composite single seat glider / sailplane finished in bright yellowRegistration "GVI" on fuselage; Kangaroo, Australian Flag and VMFG decals on vertical stabiliseraustralian gliding, glider, sailplane, moba2b, moba2c, sunderland, moba2d, victorian motorless flight group, vmfg

The object was donated by Ramsay Surgical Limited in 1944. Cylindrical metal face mask with a high neck that is open at both ends. The larger opening was placed over the patient's mouth while the smaller opening, comprising a sponge to absorb the anaesthetic and a hinged perforated lid, was used to administer the anaesthetic.waring's cone, facemask, metal, sponge, anaesthetic, ether, ramsay surgical limited, cone

This is a typical example of a flat wick domestic paraffin lamp used in households prior to the introduction of electricity.A flat-wick lamp is a simple type of paraffin lamp, which burns paraffin drawn up through a wick by capillary action. A flat-wick lamp has a fuel tank (fount), with the lamp burner attached. Attached to the fuel tank, four prongs hold the glass chimney, which acts to prevent the flame from being blown out and enhances a thermally induced draft. The glass chimney needs a "throat", or slight constriction, to create the proper draft for complete combustion of the fuel; the draft carries more air (oxygen) past the flame, helping to produce a smokeless light, which is brighter than an open flame would produce. The wick holder has holes around the outer edges. When the lantern is lit and a chimney is attached, the thermally induced draft draws air through these holes and passes over the top of the wick. This has a cooling effect and keeps the wick from over heating. The lamp burner has a flat wick, made of cotton. The lower part of the wick dips into the fount and absorbs the paraffin; the top part of the wick extends out of the wick tube of the lamp burner, which includes a wick-adjustment mechanism. Adjusting how much of the wick extends above the wick tube controls the flame. The wick tube surrounds the wick and ensures that the correct amount of air reaches the lamp burner. Adjustment is usually done by means of a small knob operating a cric, which is a toothed metal sprocket bearing against the wick. If the wick is too high, and extends beyond the burner cone at the top of the wick tube, the lamp will produce smoke and soot (unburned carbon). When the lamp is lit, the paraffin that the wick has absorbed burns and produces a clear, bright, yellow flame. As the paraffin burns, capillary action in the wick draws more kerosene up from the fuel tank. All paraffin flat-wick lamps use the dead-flame burner design, where the flame is fed cold air from below, and hot air exits above. (Source: Wikipedia accessed 24 Nov 2023) This lantern has a circular heavy green glass base for holding the paraffin. The base has a 12mm green glass handle. There is a small clear glass chimney with a fluted upper edge and some bubbles in the glass. The metal burner and wick holder has four metal prongs to hold the glass chimney in place. The round metal wick winder is functioning. There is a small amount of residual paraffin in the base. The flat wick is made of cotton.There are no markings to indicate the manufacturer.paraffin lamp, flat wick lamp, domestic lantern
