This is a genuine US Army Air Forces A-4 knit cap from World War II. It's a wool cap for maintenance personnel, a rare item that's hard to find. It's also rarely offered for sale. The color is olive drab. There are small repair marks in places. There is some soiling on the crown. The top part of the cap appears whitish in the images, but this is just due to the light; it is not actually white. A small black tag (2.5cm x 1.3cm) is attached inside. Actual measurements are approximately 24.5cm in length and 21cm in width, with a brim circumference of about 20cm. The seller's head size is 57-58cm. The fabric is stiff, but it fits well when the brim is folded outwards. The cap is also deep enough. It's a very rare item, so please consider purchasing it at this opportunity. Color... Green
