This gas burner came to me, packed with a circa 1988 red nonstick Trangia 25-5 kit I purchased. I believe it to be new / nos, as the Trangia kit was also new / nos. It has its packaging, and on the sticker it is listed as a "Butane Burner", with part number 0560151, price $29.95. I do not know which company originally sold this. Has a threaded valve assembly, for isobutane type canisters. There is no preheating loop at the burner. The burner head is marked "Grill", with a stylized "G". Brass mounting base is stamped T (Trangia logo) trangia Made In Sweden, For Outdoor Use Only, Endast For Utomhusbruk (Swedish for "For Outdoor Use Only"). There is a coiled wire around the hose, presumably as a heat shield and also to protect the hose from abrasion where it would pass through the hole in the windscreen base. Hose is approximately 520mm / 20 1/2" from end to end. It does stick up quite a bit from the plane of the windscreen base.
