Agreed the whole “forage cap is a bag for foraging” thing is a myth. That’s what your haversack is for!
Personally I quite like the 1839 style wheel forage cap, and the 1825 “chako” pinwheel is one of the nicer looking pieces of US headware.
I’m looking into buying myself a forage cap myself soon, I currently have just a kepi. I really like it but could use more variety in my headwear. Could someone do a quick break down of all the different styles of forage cap (Type 1 vs Type 2... also what’s the difference between the ‘58 and ‘61 model)?
