The B-10 is a flight jacket with a cotton shell and alpaca lining that was adopted in 1943.
It was ordered 18 times over a nine-month period as a replacement for the Sheep Shearing flight jacket, and a considerable number were produced.
Because it was produced in large quantities during the war, there are occasional small differences in the details depending on the delivery contractor, and occasionally there are examples without epaulets. While
the details are unknown, this was likely intentional, and the fact that there is a mixture of these jackets within the same order number suggests that they were produced as some kind of option.
