I have a ("the"?) red Ainsmith. It's not as stiff as some of the BF2s, but about the same thickness.
Note that there's a bit more of a "W" on the sleeve of my Ainsmith than there is on ex-Rob's. The McBride has a very distinct "W." And while the pose is the same for Meyers, McBride, and Ainsmith, the picture isn't quite the same. Look at the way the folds fall on the uniform and the sock patterns. These were not just one-pic-for-all like the E-91s.
Is the Stirling catalog worth picking up? I see one on eBay and one on Amazon.
