Jason,
Contractors made brogans in both smooth-out and rough-out leather. I've seen original examples of rough-out brogans that were blackballed so heavily that the rough uppers looked shiny and smooth. It's also how I treat my own pair.
As for reproductions, I listed some top notch vendors below. They're more expensive than standard sutler-row varieties but the quality is going to be better and they are guaranteed to be made by band in the USA by a skilled artisan rather than mass produced. In my opinion you get higher comfort, quality, longevity, and authenticity for your buck. I own a pair of Missouri Boot & Shoe #JB-2 brogans that have lasted me for ten years without any repairs aside from replacing the leather strings and keeping them well blackened after every event.
