The answer was very simple in the end, if you looked at all the angles. This detailed post will likely interest only people with early 1970's model Airstreams who want to know what the inside of their closet doors look like. It is for them that I write this. The question at hand was how to bring our closet doors into our new all-birch interior color scheme and meet some specific criteria.
1. look like they belong with the new birch bulkheads and beech counters
2. remain in keeping with the aluminum extrusion construction of the early 70's Airstreams
3. be easy to open and easy to latch
4. stay securely shut while en route.
