I guess that this K could lose another 2 Lbs or so by trimming off the side lips and close welding the two half's together for strength.
It does look like an original untouched K to the fast moving eye though.

But now since getting off a plane, I just noticed that you have trimmed the lips off and it looks very nice from this point.

It would be sooooooo nice to have a factory lightweight stainless K, but at $14.500K, those K's are a little out of my league. LOL.
