John - that's an intriguing find. Looking forward to seeing your photos.
Me too guys! I focus primarily on lightweights, but do not recognize this hat. The cloth covered leather sweat (if that is what it actually is) reminds me of a Knox Vagabond I found a while back, and my Dobbs Doublelife (being a pinhead does have some rewards). See below.
I am hoping for a Cavanagh version that resembles one or the other of these. It may just be a ribbon sweat, and I'd be nervous about it being a woman's hat if it was not co-branded Marshall Field's men's store.
