One lamp that recently left my collection due to sales abroad is this rather rare Primus 1084 model. This is an early variety with a rounded blue top adorned with a nickled disc with text. The later variety has a remarkable new style top which is not in abundance either. A copy of the well bred Petromax, although equiped with their own system of a starter, this model is perhaps the swan song of Primus as a lamp maker. Like always, the difference is in the details..... with an exclusive pre-heater that according to experienced owners had its faults.... and a remarkable new style turning wheel... a butterfly styled fuel cap and stopped connector for a pressure gauge... plus a tastfull ornament on top proclaiming its maker. Next to an engraved "Instant' in similar fashion, suggesting how quick this lamp could be actuated, this side of the bottom fount mentions the model number and the modest claim of its lighting capacities. Even if well used, one cannot be picky to pass any 1084 you might, but then might never find on your way. The rare and imo tasty colour blue of the top should help you spot it when that lucky day arrives. While Primus mentions in their catalogues a fitting top reflector for this model, they seem even rarer than hen's teeth. However, being a Petromax copy, just such a shade will fit and makes for a very classic presentation.
