Hi Andrew,
Yes, I thought they did a pretty good job with accuracy. As I said, the repro patch is a canvas material which is quite sturdy, but still flexible.
Here's a link to the film company that is making the documentary and info about the film (including a couple of photos and a short film clip):

They did much of the initial filming in Northern Australia at the actual crash-landing site on the Anjo Peninsula, the northwest part of Napier-Broome Bay,
Kimberly region, about 60 miles northwest of the Royal Australian Air Force landing strip at Drysdale Mission, near Kalumburu. They flew the widow of the pilot of "Shady Lady" from the US to the site and she is in the opening scene. While in Australia, she was presented with a Presidential Unit Citation for the Shady Lady crew by the US military attache in Sydney. Most of the rest was filmed in England, Massachusetts and Florida, US. They filmed the B-24 interior sequences aboard the Collings Foundation B-24J "Witchcraft".
I don't know what brand of A-2 he used, or how many. I do remember him telling me that he went online to purchase them. I'll email him and ask. The film isn't released yet (should be by the end of May) and will be available on dvd when it's completely finished. I'll let you know.
