Wow! That is very, very nice! One of my grail/bucket list guns in all its "as-new-in-factory-box" glory! Ya gotta love it!

Coincidentally, I just picked up one myself last week under some pretty crazy circumstances. See here.

Mine appears to be a year or so later than yours. Serial number on mine is A2128xx.

Now I'm down to just two grail/bucket list guns left before I can go on to my reward... to that big forever gun show in the sky! Just need to find the right BHP and a suitable K-22 and I'm good to go!
