I am including pictures of my '64 Overlander's door locksets. It was equipped from the factory with a non-locking knob-set with a deadbolt. These are OEM replacements for the originals that failed last year.
Door Edge View
This installation is probably very similar to what would have been available on a 1959
Traveler with the door-within-a-door. There were differences in the knobset latch assembly that resulted in revisions to the door hardware in the door edge view which left the two holes where the original had a nylon insulator boshing collar that couldn't be modified to work with the new lockset.
