Cap eagles in WW2 came in different sizes, styles, materials (gold plated, brass), and were made by numerous manufacturers. The eagle supplied with the Flighter is a modern reproduction and marked “Acid Test Gemsco” on the rear. Aside from the obvious shininess, the pattern is one of the common WW2 variations, and was often seen on original caps. It is easily removed by one round nut on the rear and could easily be swapped with an original.
As is common in original caps, the celluloid sweatshield in both of my examples has carmelized and all but obliterated the Bancroft label. Society's cap features a color label behind a clear sweatshield (intended to keep sweat and oil from staining the cap fabric). I imagine this is how Flighters looked when they were new, but I've never seen one in “like new” condition in my 30 years of collecting.
It takes careful examination to determine the actual color of the interior lining in the originals. In both cases, the yellow satin liner can only be observed in the center front of the crown. The material used in the SBHC Flighter appears to be a modern match and no discernible difference can be noted.
The color of leather varies with age, exposure to heat, and contact with hair oils and sweat. The Flighter logo embossed on Society Brand's closely matches the originals, although the modern leather is slightly thicker and has a different ventilation hole pattern. Instead of holes encompassing the band, there are perforated sections. I know there were variations of sweatbands throughout the production run of Flighters, including the placement of the Flighter logo, and overall the execution is well done even if not an 100% match to the originals I have on hand. This is not to say it isn't an original pattern, it just doesn't match the samples I have.
I think the amount of research into the correct pattern of Bancroft Flighters is apparent in this model, and is replicated as closely as possible using modern materials. I could not find any major faults with the cap, which wears nicely and fits well. The visor retains its shape and can be easily manipulated without damage. Will modern leather hold up for 70+ years? Only time will tell, but I think that once it is broken in and obtains a patina of wear, it will look even more authentic. This is as close as you can get to a “new-in-the-box” Flighter, and I believe this reproduction will only get better with age.
