Now this Henry is special!
I bought this with the other one and at the time didn't think too much of the contoured action.
All I knew is that I needed to have them regardless of their configuration.
Once home, it wasn't long before my curiosity was rewarded and I got a good look at what I had just bought.
Alex Henry falling blocks chambered in 450-400 are quite rare but the detachable barrel design on this one pushes it into stratospheric rarity. Perhaps the only one made and for sure the only example known to Winfer or Kirton (as far as their publications state).
