Here are some photos of the finishing of the barrel.
The first three photos are of the unfinished side (I worked on the left side just for a comparison.) Note the two rings on the barrel where the lathe advanced abruptly. It is far less noticable but there are some pretty bad tool marks for the entire length of the turned part of the barrel.
Also no attempt was made either at the factory or by the original assembler (the pistol was a kit) to smooth out the barrel. In a different thread I talked about the lines in the contours of the lug end of the 1860/61 barrel. To me these lines make the pistol look unfinished. I think that gradual transition are vital in giving the 1860 its graceful appearance.
I worked on the left side of the barrel with a file and with some course paper. Obviously the metal is not ready for blueing but at least the rings and lines are gone.
