This idea needs more data (more serial numbers from all these models) to compare and see it if holds up. It's merely an untested thought right now.
Congratulations on your "new" 22' Liner. It appears very complete inside and you are very fortunate to find one in that fine condition. Have fun with it!
Thanks for the reminder on the second set of numbers, I had read that somewhere but had forgotten it.
I don't think the last number is the size - at least according to a document posted on Airstreams historical archives/service section, each size model had it's own series of starting serial numbers, 1xxx to 7xxx series, but who knows if that holds true for the early '47's, or even that the model number could still maybe designate the size as well as it's own serial # series - who knows. Just like anything on the internet, just because it's online does not always make it a fact:
Congrats on the purchase Sprouty. Good find and a good deal I think. Got your PM - Yea, for sure we'll have to compare notes since we are both in Wisconsin - small world. I'm just south of Sheboygan in Manitowoc, so not that far from you. Wisconsin seems to be gathering a nice collection of these old beasties!
