Welcome to the world of Vintage Airstream ownership!
One problem the key for the deadbolt was missing and during the 400 miles home the door flung open and punched a hole in the skin. Talk about heartbreaking. How the heck do I fix it???
This is one of those nightmares that many Vintage coach owners have had to deal with. After having had my door knob and deadbolt rebuilt, I wasn't particularly worried about having the door fly open in-transit - - but after having the coach polished and Plasticoated at the Ruth's (P & S Trailer Service in Helena, Ohion), the tumbler failed in the deadbolt and it couldn't be secured - - less than ten miles from the Ruth's, a strong gust of wind sent the door flapping and the knob eneded up puncturing the side of the coach. A cell phone call to the Ruths with the good news that they could probably repair it that day - - towed it back and the repair was a very inconspicuous square patch with a rubber bumper that you can see in the photo below - - they were very cautious to seal around the perimiter of the patch with Vulkem - - it has been nearly three years and the patch has remained waterproof.
Good luck with your repair - - there is an excellent modern replacement for the early '60s factory deadbolt - - Florence in the parts department at Ace Fogdall RV in Cedar Falls, Iowa located the replacement deadbolt for my Overlander.
