I have no pics unfortunately, but I recall it was just as beautiful and consistent as any other Webley blueing, and the non-glare aspect seemed appropriate for a hunting gun.

It shot VERY hard, and sounds like it might have been rather rare to boot! One of many I regret selling over the years.
I have a Vulcan of the same series with the same finish on the tube. It was possibly cost cutting at a time when the British airgun manufacturers were feeling the competition? However, the barrel has a highly polished finish.
