Hi Guys,
I acquired a Brumbow last year and wasn't too happy with how it shot.
I bought a WW kit and proceeded to strip it down.
Interestingly, the compression tube seems to have a copper, or similar inlay in it. As well as this, there are tiny lateral lines. Now these could be from machining, or the piston juddering, or they maybe are meant to be there.
Can anyone shed any light on it, before I go an hone the cylinder?
I have pics, but don't know how to attach, as I don't use image hosting
Thanks in advance
