Thanks for those pictures. I'm still not sold on the black paint on the emitter.
I think the V3 may have been refurbished, possibly only partially. The reason I believe this, is the clean "booster" section, the bright copper paint on the neck. Whereas the V2 has remnants of black paint on it, and the copper/aged brass looks to have been added over the black. I know some think the V3 may have black paint on it. But to me it looks like it beat, and scuffed up, much like how the Yuma looked in its stunt form.
