Never seen that double windflap used again until the 1980sWow. I saw this detail, obviously, but could not spatially process it. So I just skipped it over.
The second flap was a solution to a problem no one had thought would *be* a problem.
The question is: was it carried over into another jacket type? Or did the putative Goldie 31-1897 adapt it to a "jetted" strip?
In view of the fact that all known A-2 contracts up to 1938 at least, used the jetted strip LH side zipper system, I'd have thought it's fair to assume the the Goldsmith jacket did too.
