This is an Australian Austramax Lantern and appears to be an early variation of the 3/300. The hood is red enamelled steel The glass is bulbous and marked with Austramax (in red letters). The font is all brass (not a steel base). The tank has the additional blocked-off port The font is stamped twice with the Austramax logo, once under the filler cap and the second under the pump tube. Frame and base plate is brass with nickel plating Hood retainer and acorn nut (brass) The pressure bleed and filler cap are brass The pump assembly and retaining screws The control Knob is the round wheel type The vapouriser and needle with brass mesh insert. Note the pricker was broken and has been repaired with a new 0.15mm steel wire. The NRV is not original to this model. It had previously been replaced with the modern Austramax NRV. Note the nut on the screw is swaged on after the NRV was assembled. It would be better to replace the seal by prying the old one off rather than disassembling the NRV (like I did) The burner (nozzle) is in two parts with wire mesh. The burner came with a very fine mesh that looked like it came from a kitchen tap filter. I did get it to work when I increased the pressure significantly. But I still think it’s not right. I replaced the mesh with a larger stainless steel mesh from a kitchen strainer. The wires were 0.22mm Dia with approx 0.7mm between wires.
