Hi! It seems to be over ten years of my earlier post here, so it's time to write here again. So, I just bought one nice old Primus. - I paid 10 Euros for it (not too bad, I think). As you can see, original condition was a little bit, well, black, but I am working on it. This far I have removed a lot of extra tin around the pump and legs, and I also have slowly started to remove that "patina". I usually like some signs of age what it comes this kinds on objects, but too much is too much, and so I have decided to clean it totally - especially as there are no dents or anything like that. I also seriously plan to make it work like new, and if I am lucky, I will take it with me to my next wilderness expedition to Lapland here in Finland later this winter. However, I would like to ask, whether anyone could give any accurate information according to its age. Personally I can say it's quite old, probably early 1890's, as there is nothing but "Primus" and "Patent" stampings on the upper shell and that usual "Bahco" stamping at the bottom, which in this case isn't placed in the centre. Also, there are typical "Lindquist patent" and "B.A. Hjort" stampings on pump & tank lid. Flame screw is unstamped. Roarer type burner has hexagonal nut. Pan supports are long model, almost one cm longer, and reaching nearer to the burner, than on my other (otherwise almost similar but late 1890 - early 1900 Primus, which has no. 1 stamping and stove logo between Pri-Mus text). Please notice the shape of the pump knob - that is something I have't seen earlier... Could it be "fake"? - Pump is otherwise rather typical removable model and it will work after my order of those leather cups is going to arrive... Regards!
