Hello
Barber and Lefevers are not common but I would call them rare. I see about one or two a year for sale. They built around 300 of them from 1874 to 1876. Some are confersion guns and others are guns that they built. I have 37 guns on my list and they range from #5081 to #5393. Keep in mind there are some Nichol & Lefever guns in the low #53XX range.
Lefevers that are rarer than Barber Lefevers are Ellis and Lefevers 7 recorded, Dangerfield and Lefevers 12 recorded, John Nichols guns, JW Livingstone guns, and Auburn lefevers.
