This is an Australian Austramax 3/300 Lantern with a stainless steel based font. This appears to be an early variation of the NEW stainless steel base font model. There are several differences between this lantern and other variations I have seen. The font is brass with a Stainless steel bottom (lantern was over cleaned by a previous owner) The font is stamped twice with the Austramax logo, once under the filler cap and the second under the pump tube. The pressure bleed is brass but there is a plastic insert replacing the needle to make the seal. This plastic insert has cracked and leaks air. As an interim fix I have inserted a viton seal under the plastic insert until I make a new one. The knob on the pump is aluminium and so is the hood nut Other general details. The hood is enamelled steel in blue with white speckles The glass is bulbous and marked with Austramax. The burner (nozzle) has a pressed screen rather than the earlier wire mesh The vapouriser and needle with brass mesh insert. The control Knob is the later pointed style (not round) The handle is the later square shape rather than the earlier type with a rounded profile The pump piston is an ‘O’ ring design The NRV is larger than standard primus type and has a screwdriver slot rather than the raised 5mm head for removal.
