"The Broadwater range of gas fuelled marine stoves is a world leader in quality, style, reliability and durability. The Maxie and Tudor ranges include gas and spirit fuelled burners. The stoves are proudly Australian made and have been manufactured for over 75 years".
But I don't hold out any hope of success. It would be easier to make our own:
I entered 'copper stopend 54mm' into the eBay.co.uk search box, and very quickly found the basis of the burner chamber. Add in some sheet copper to form the preheating cup - an easy job. Add in some 6mm copper tube, that must pass through the burner chamber and then turn back on itself, to be squeezed shut and then re-drilled with a 1mm hole. Make a 10mm hole in the burner chamber, opposite the 1mm hole. Add a 6mm needle valve with compression fittings. Buy a MAPP gas torch and some sifbronze rods. Add in a little bit of metalworking skill, and some time, and you're there.
Total cost for materials for two burners: £39, free carriage
Cost of one Maxie burner £65 + carriage
