I had replied to the message you sent me and it seemed like it didn't send so I kept replying so if you get a million replies I apologize.
Congrats on your Airstream purchase.
And I love the video. There might be one frame to pause on in that video but be assured most people on here will tell you a ton based upon that one frame. HA! It is being analyzed as we speak by a team of highly trained nonprofessionals.
I have the identical trailer as yours but in saying that there are variations in styling in trailers from same year. Not sure if yours is a single or double axle. Mine is a single and I think after 55 they changed to double. Ya a 26' Overlander with a single axle.
It can be fun to look around inside old trailers and see what has slid under a stove or between a cabinet and wall. I found many hints as to where mine had been. A 1966
mechanic's business card from Pasadena California. A toy bow and arrow set still in box accidentally shoved way back in a storage area. A semi rare solid silver dime from early sixties worth $6- and a 12v
light bulb from Mexico.
After researching the almost faded Wally Byam Caravan numbers (824) on the front and back I discovered my trailer was owned by an Ontario couple that took it to Mexico via California on the 1959
Mexico Caravan tour. Their running light must have got busted off and they replaced it in Mexico hence the Mexican made bulb.
So keep a sharp eye for clues as you dismantle because there should be hints as to its history.
Oh another thing is I kept everything from the interior until I was completely sure I would not need it. Old walls will be your future templates for new ones.
