If you are thinking in terms of a Vintage Airstream, solid hard woods weren't used to my knowledge (1950s-1970s). The cabinets were plywood with various hardwood veneers as the top layer. The solid hardwoods didn't come into play until sometime in the early 1980s if my notes are correct. The various tambour materials were a feature of the 1970s coaches.
My notes indicate that Airstream never used acrylic of any kind for windows in Airstream coaches, but did try some acrylic products for windows in Argosys, the Minuet in particular. You might find Lexan or Plexiglass as an aftermarket installation for front windows damaged during use or as a replacement for the Corning Glass Windows utilized from 1966
Porcelain for bath and kitchen fixtures to my knowledge would pre-date 1960
with the exception of the toilet. Some Airstreams between 1960
had porcelain kitchen sinks, but it seems that by 1964
most of the kitchen sinks were stainless steel. Porcelain toilets were used through at least 1964
and possibly later - - the problem today would be find necessary replacement parts to keep them functional.
So far as the dinette arrangement is concerned, at least as it applies to 1960s coaches there weren't many offered in stock floor plans. The Overlander during the early part of the decade had a free standing table that was replaced by the "credenza tables" that would continue through the 1970s. It seems that what few were offered were in the smaller trailers under 24 feet. I am not as familiar with Airstreams beyond 1975, but do understand that the dinette was an offering on some of the larger trailers starting sometime around 1980.
It seems that the dinette was far more available option in the Argosy coaches as it was illustrated as a standard floorplan in a number of the sales brochures that I have seen for 1977-1979 Argosys.
Good luck with your search!
