Welcome to Airsteamming. There are a lot of folks who love their Ambassadors. Many of them are renovated and back traveling the country. Enjoy it. You gotta order Tim Sheppard's book "Restoring A Dream". It's all about a 1960
Ambassador. Tim is the creator of the Vintage Airstream Podcast (VAP). He and Colin Hyde do a great job with it. It's all about old Airstreams.
It appears your serial number is an early 59, maybe the 11th one made. You can take it from fair condition to excellent condition with many hours and dollars. But I told my wife that we are likely to get our money back when we sell or Trade Wind. You know what I mean when you were searching for your trailer. The ones that are renovated can be up to $20,000 easily. The ones that are professionally restored are worth much more than that.
Get ready to enjoy a big project.
