Bos_Trok, excellent question my friend!
I love my '63 Alaskan and, as such, have been trying to outfit her with as many "time-period-specific" items wanted that I can find. I've scoured Bay Area antique shops with my youngest son (the heir apparent to our Alaskan as he's been my partner in crime in her buildout).
What you've notice in those epics is actually a '1963 mfr multi-function torch (aka flashlight) manufactured for the Great Northern Pacific Railroad corp specifically for it's Line Mechanics. My son gave that to me last year for Christmas and I've since gutted the unit and rebuilt it in LED. In fact, it's sooooo incredibly bright that its a bit frightening to other campers. :-D. The unit has a 'glow mode' to light up an area in a soft yellow ambient light and another side with >750 Lumen blind the campsite next to you lighting.
Wrt time.period.specific, our latest search is for Korea-era, sectional metal food trays. My parents had a 1969(?) CO when we lived in Alaska ('70-'73). To this day my most vivid memories of that camper are 1) of the light above the table - and our camper has a near exact replica from '63 - and 2), of the metal food trays that my father (then 1st Lieutenant) freshly back from Vietnam had outfitted our camper's galley. Needless to say, I'm on the lookout for similar trays for our Alaskan.
