Marrakai:

That kind of finish IS characteristic of Jeffery rifles - and most other pre-war British rifles as well. I've seen quite a few myself. On original pre-war rifles, the barrel striking is usually faintly visible through the blacking under a bright light, such as a camera flash. There's nothing "rough" or "lazy" about the finish in the photo. Generally, with a few exceptions, that's the way it was done in the pre-war years. Recent, incorrect refinishes are often easy to spot due to the excessive polishing.
