Hmm...you see chestnut as a boot, I see it as a wingtip. We both agree it's not a Dover! I tend away from boots in straight calf. With the extra expanse of unadorned leather, I prefer something with more surface interest - a grain, suede, or cordovan...which doesn't have a rough finish like the others, but develops waviness over time and also just looks different from the normal calf shoe and is therefore more interesting purely by virtue of its rarity.
I have talked myself into the burnt pine on the Dovers. Done and done.
