The 70's & earlier Sveas did not have a "self-cleaning" needle on the burner, like the newer ones do (as pictured in the parts kit photo). They were cleaned with small external wires on a thin piece of aluminum. Unfortunately, Optimus no longer stocks that part. However! At some point in the late 70's, early 80's The self-cleaning needle system at the bottom of the photo was added to Sveas. If you take your Svea apart and finds parts that match those in the photo, this kit will work. The big rubber gasket at the top of the photo is for the fuel cap and should work fine with any Svea.
Our rep says that he has a 1979 Svea and it does work with the Optimus Svea and Hunter spare parts kit. he suggests that you take the jet off (the round brass piece with the square top, in the left bottom corner) and look inside and to see whether there is a cleaning needle or not. If it is present, then your stove will take the kit. If there is no needle, you will need the small wires mentioned in the previous response.
For what it's worth, I still have the box for my SVEA. I purchased it sometime between 1974 and May,1976. The box is labeled "SVEA 123 / New-now with self-cleaning device." Apparently they weren't labeled SVEA 123R when the version with cleaning device first came out.
Here is another picture of the package http://www.outfittercountry.com/images/product/large/5682_1_.jpg If you identify whether you have the 123 or the 123R you should be able to know if this package is compatible. Here is a video explaining how to tell the difference http://www.youtube.com/watch?v=RSffVA0Va54 and here is a link showing what the parts kit for the 123R looks like http://www.wildernessdining.com/as733441.html
