Greetings, All, Many years ago, I found an old Optimus burner (#207), and fuel tank, which was obviously designed to be a part of a cooking Range. I've always planned to so something fun with it, but ended up putting it down in a large cabinet, down in the Hobbit Hole, and... well, forgot about it. Until recently.... @gideon posted a great thread about making an steel stand for his Radius #10, and a bang-up job he did of it, too!! Radius-10 and self-made stand Besides enjoying his post on it's own, it also reminded me that I had the old Optimus tank and burner down in the HH, "someplace". Today, I dug it out, and have looked in the Stove Reference Gallery, and Reference Library, trying to find out, exactly, what it is, and when it was made. After doing some reading, and perusing here, I "think" that it's the left-hand burner/fuel tank of an early Optimus 181 Range. I would guess it was made sometime between 1935, and 1939. Here's what I have: Nice to have the original priming setup, still insitu. Some of the sharp-eyed amongst you may see the prominent casting on the regulating valve, into which the stuffing box nut is screwed, "OPT. 207" Here's another shot of it, in case you did not see it in the photo above. Back when first receiving this stove, I replaced the missing inner and outer caps with what I had on hand. The outer cap may be right, but the inner is obviously not. Though it should work with either cap, and I will replace it with what I think is it's proper inner, without the 3 sets of holes around it's top edge My first clue that the drilled cap above, was not used on this stove, originally. You can see the small, brass keeper nut, underneath the burner, which, originally, was used to keep the stoves centered and supported in a single, or double 181 stove. I am guessing this is the left-hand burner of a double 181. Sound right? Besides replacing the missing flame spreader caps, I also replaced the rock-hard pump bucket leather. I think this one was made by our wonderful Brother, Sefa, in Turkey! Now, as you look, again, at the burner and tank, doesn't it look like a left-hand side attachment to a double 181 stand? So, what do you think, Fellow Stovies? Take a look at the following Reference Library photos, compliments of @optipri , and see if you agree that this is part of an early Optimus 181, dating 1935-1939. https://classiccampstoves.com/threads/1935-optimus-no-181-182-range.28674/ https://classiccampstoves.com/threads/optimus-kero-gas-range-1939.39193/ Now, all I need to get is a proper stand for this setup, or like Gideon, make, or modify, something, myself! Much to consider, for sure! I welcome all comments, suggestions, or information, if you have such to share, my friends!! Thanks, very much, and God Bless! Every Good Wish, Doc PS - I do have the original regulating wheel and spindle, but removed it and bagged it, with a bunch of others, for safe-keeping. When I begin working on this project, I will retrieve said accouterment, from said bag, and install it in it's rightful place. Sorry, I forgot to get it before I posted this! OOps!!
