This is a very small«museum» that does not charge any admission. You have to drive a few minutes out of town to get there. They have a good collection of military paraphernalia which includes pistols, swords, rifles, uniforms, etc. Given that it’s 100% free of charge(a little donation can is present if you’re so inclined), it’s worth a brief(like 30 minute tops) stop. It’s attached to a gift shop which has typical tourist merchandise focusing on the civil war and/or Gettysburg. The house(the museum is located inside a house) was one of Lee’s «headquarters» during the battle.
