I am getting ready to rebarrel a Pedersoli 74 Sharps. I have a Green Mountain 32" Sharps #4 profile barrel that I bought probably 20 years ago. I want a more slender profile that is half round. I have been trying to find a source for Sharps barrel profiles on the internet with no success. Anyone have any information or have a Sharps that has a 32" half round barrel they can measure?
