Without knowing the relative availability of Silk Waste as opposed to Raw Cotton in USA during the 1930s it's hard to be subjective as to when Cotton overtook Spun Silk as the preferred choice for an A-2 lining as legend would have it by late in that decade............assuming that is the case.
What we do know is
(1) The original spec choice in 1931 was Spun Silk FACT
(2) It's not easy to tell Spun Silk cloth from Cotton cloth if the weave spec is the same FACT
(3) The early contracts were relatively small and it's logical to assume there was a reasonble supply of Spun Silk available in 1931 otherwise the Air Corps would hardly have been likely to specify this material. FACT
(4) We found Spun Silk to be less that double the cost of a similar grade Cotton from the same weavers while it was available, not a major factor in the costing of an A-2 Jacket FACT
(5) Assuming (3) as factual, here seems no good reason for using a non specified lining while the specified lining is not only superior but also readily available. LOGICAL IF NOT PROVEN FACT
