Thank you. After elbow grease, I found "AJ" so its 1945. It also had "14" under the letters that the date chart didn't discuss.
Regarding the Primus date coding; no one has yet been able to de-code the meaning of the numbers following the year letter(s). One suggestion is that it is an identifier of a particular work group or production line. Hope this helps. Best Regards, Kerophile.
Thanks. I'll probably not use this stove except for show firings so I'll clean it up as best as can be done. Some more questions: What is the material of the top plate and how should it be cleaned or maintained. It seems like a pressed steel since there is some corrosion at the joints where the legs attach. Can the tabs holding the top plate to the leg struts be bent to detach the plate or should they be left alone? The vapor generator tubes are brass in some photos. Before doing some damage, should I try to clean these parts? Thanks again to all for your generous advice.
Hi, Here is a link to more than you ever wanted to know about stove restoration: https://classiccampstoves.com/threads/3963 The top ring, or trivet, is a pressed steel component. The original paint soon burns of, and combined with the effects of heat and moisture the trivets do rust away in time. They are consumable items and were probably replaced several times during the lifetime of a domestic stove. Depending on how many times they have been bent before, and how corroded they are, the securing tags can be bent back sufficiently to release the top from the legs. If they break off you can reattach the trivet to the legs with fine wire. How about showing some photos of your 1945 stove? Best Regards, Kerophile.

Hi, you can upload images or files from your own computer to this thread, or in the Stove gallery, if you wish. In the case of this thread: Click "Reply" Below the box for inserting text, you will see an option "Upload images or files" Cick this and a pop up window will open allowing you to browse and select file(s) off your hard drive. This window (The 'File Manager') allows you to add, upload and remove files. To upload a file, click Browse and select the file from your hardrive. Then click Add. Review the files you have added at the bottom of the window. When you are done, click the small icon to insert the code into your post. The icons are labelled Thumbnail, Medium or Full & you may be given more than one choice depending on the forum. If there is no icon proceed to the next step. NOTE - Do not REMOVE files from the file manager once you have finished - if you do they will not show. Click Finished to add the file to your post. TIP To add a space between any text & your pictures add a couple of spaces (hit enter twice). Spaces between pictures are not required - if you add them between thumbnails they will appear as a column rather than a row which will mean more scrolling. Please note that your administrator has set a file size & quantity limit. Regards, Kerophile.
Hi Dave. Good advice from Kerophile. The image file size limit for this particular forum is 100.59KB. If your images are greater than the limit (probable), then use the Optimiser option in the blue bar at the top of the screen: 1. Click on 'Image Optimiser'. 2. Click on 'Choose File' and select the jpg image file on your PC. 3. Click 'Upload Image'. 4. After a while two images will appear. The one on the right will be your original, the one on the left will be the new optimised image. The KB size of the image on the left should now be smaller than the image on the right. The KB size on the left must be smaller than 100.59KB. If it is larger than this, go to the 'Image Quality' box and reduce the figure. Then click 'Apply Changes'. The image will reappear with a lower KB value. Repeat if necessary to get below 100.59KB 5. Once you are happy with the KB size, click on 'download this image'. A copy of the image will be saved to your PC (probably in 'Downloads'). By default it will add _opt to the filename to prevent accidental overwriting of your original file. For example if you upload mystove.jpg, when you save it the filename will automatically be mystove_opt.jpg. 6. You can then upload the optimised image into your post using the instructions given by Kerophile above. You don't have to use the optimiser to reduce the KB size. You can use any photo editing software you like Of course, if your image file is already below 100.59KB you don't need to optimise it all. Hope this helps. Regards, Terry
Some photos with different camera lighting and angles. As I've been wondering, I stopped polishing at the spirit cup since I wasn't sure about the tubing. It's a complicated structure, not a round tank. I also shot the top plate with the rust at the leg joints. Leave it alone? Thanks to all for your help for a new owner of an old stove. Dave
Hi Dave, a nice post of a very good stove. The stove and pan-ring are in excellent condition, particularly for a 1945 model. The pan-ring will detach easily with a firm pull, as the attachment clips are designed as pop-on, pop-off. You can then remove any rust if you wish, and re-attach. Best Regards, Kerophile.
I was thinking of oxalic acid for the rust, which I think is also in Red Bear brass polish. Any idea what the gold tone finish is on the pan ring? As in I don't want to remove it along with the rust. Thanks
Hi Oxalic acid is a poison and needs to be disposed of very carefully. Phosphoric acid will remove rust from steel very effectively with much less hazard. Some pan-holders were finished with a gold coloured varnish or paint, others were electroplated with a brass finish. Neither stands up very well to the demanding conditions experienced by a pan-holder. Your example looks very good as it is, and if this was my classic stove I would leave it "as is". If and when the finish becomes unacceptable you might consider using one of the modern heat-resistant paints sold by automotive suppliers. Best Regards, Kerophile.
Yes. Don't chew rhubarb leaves. "In humans, oxalic acid has an oral LDLo (lowest published lethal dose) of 600 mg/kg.[15] The toxicity of oxalic acid is due to kidney failure, which arises because it causes precipitation of solid calcium oxalate, the main component of kidney stones. Oxalic acid can also cause joint pain due to the formation of similar precipitates in the joints." http://en.wikipedia.org/wiki/Oxalic_acid Best Regards, Kerophile.
Hi. I usually wire brush mine. If you are using the stove the burner tubes will darken over time anyway.
This will probably be a display piece, fired on occasion to show how it works. I recall that the tubes are also brass and can be polished but it seems like a .... task to get them up to bristol condition. I took a soft shot at undoing the bolt/nut at the joint with the cup but it didn't budge. I didn't want to mess up things. At this point, I'm trying not to do harm in the interest of restoration.
