Looks good. Finding and older Airstream like this that has been sitting idle for several years without any major changes that have been made to the interior or exterior is rare. This is what you are looking for if you want to refurbish one as you are indicating. You know what you have and any changes from original layout should be mush easier. There are a number of very good threads in the "interior" section of the forum. The old interior pieces and appliance may not be worth much in dollars and cents, but as a source for parts for those on the list that may be looking for someting to fix or complete a project they are working on become invaluable. I have completelly refurbished the interior of my 1976 31" Sovereign
over the past 9 years and I carefuuly removed cabinets, doors, appliances and other items that I was not going to re-use and then offered them to forum members at no cost other than the shipping cost. Although I could have sold some of these parts for a small amount of money I have gained much more in helping someone who needed a part that in some cases was just no longer available. Something to think about.
But before you get started on the interior and evne some of the exterior items let me be one of the first to say, start this project with your Running Gear. That's the Axles, brakes, shocks, tires, hitch, and 7 pin trailer/TV connection. If you plan on traveling you want to have your running gear in top condition. Go to the running gear section of the forums and start your research and ask questions.
Good luck and enjoy your Airstream project.
