Are there any companies similar to Pedersoli, Uberti etc making Rolling Blocks, High Wall, Sharps, or Trap Door single shots in .50-70 that are available in North America? I see some of what I consider Custom makers doing them in $2-4000 rifles, where the more affordable Italian reproduction guns seem to all be in .45-70 or longer, .38-55 and other more modern cartridges.
