Here's two of the three photos from the article by Todd. The top caption says "Collapsible leather forage cap in the collection of the National Museum; shown open." The bottom says "Same, shown folded flat." The third photo is of a cloth cap. I had to reduce them 2/3 for posting.
I have a copy, and would be happy to send a copy of the article. Send your address to the email above.
