Airstreams Annual Production

How many did they make each year? I have done a fair amount of research on this and I can't find annual production numbers. What are the annual production numbers? How many of each length? Each model?



Frequent scanning of the classifieds and a loose tracking of how many trailers are for sale by year, by model and by length has led me to the following speculation:

• There are sharp peaks and valleys in annual production.
  


• Until fairly recently there were many more longer trailers, i.e. 28' and up, produced than shorter ones.
  


• Production seems to have been particularly low in the late 80's and early 90's.

This is something that I'm very curious about. Production numbers can have a major impact on values. When you have scarcity plus desirability you get higher prices. As an owner of a '90 25' Excella I have watched with interest the frequent Wanted to Buy ads for trailers meeting my specs. My trailer is not for sale and, other than for agreed value insurance purposes, it's pretty much academic, but it's nice to know.



I spent many years in the early Porsche world and there production figures are known exactly. I can't believe that AS doesn't have these figures in musty ledgers somewhere. Or can we extrapolate from serial numbers? Anyone?



Cheers,
