As aCowboy Shooter, I love my Henry. But, they are well over $1000 and have all modern markings. The only appropriate Henry is the 1860 Henry, typically made by Uberti. As far as a reenacting Rifle, there are rare events where they would be appropriate and even rarer than that for Confederate impressions. Theye were not in great numbers during the war.
A better and much cheaper plan would be to spend the money on a good defarbed Springfield or Enfield. Then he would be mostly right for any impression, and could go more Progressive in the future. And you could save several hundred of dollars. Also, 1860 Henry blanks still sue the .45 or .44-40 brass, which as we Cowboy shooters know is getting quite expensive. Paper tubes and powder are MUCH cheaper.
By no means would I get a lever action from the Henry company, for those are all 1873 and beyond.
