Rare Vintage National Airways System Stock Certificate Air-King Airplanes. I’ve tried to find out some information on the company and the planes but for the most part have been unsuccessful. I believe them to be quite rare and would be a great addition any collection. Stock is creased from being mailed or storage. There are a couple of small tears about a quarter inch long along the fold creases at the top. There is some general wear along the edges. The letter is in good condition with just fold creases. I have taken a bunch of scans. It may look like a couple. Pictures but I have scanned it twice to show the upper edge and the bottom. Was a little larger than the scanner bed. There is a watermark on the paper. I think it says COURIER BOND. What is pictured is what is for sale. Nothing else is included unless otherwise stated. Canadian Residents will be charged 5% GST. Typically add a couple of days to the actual transit time. Once it leaves our hands, we have little control of it. The cost represents the weight , size of the package and the destination. Only items pictured are for sale unless otherwise stated. If there are more than a quantity of 1 item it is assumed that the picture is indicative of all the items unless otherwise stated. This applies to both the item and any retail packaging. We’re happy to answer your questions, but we can’t answer complex technical questions about most of the things we sell – we just sell’em, we haven’t used’em personally, other than a quick test to verify working condition.
