Offered here is a hard to find LEFTY Newport Art of Putting in the tour triple black finish and initials B.M.

From Vog: Over the years, as a collector, I've had to be a bit of a detective. This has been authenticated as a "made for the tour" Newport in a 3X (triple black-milled face, polished sole, matte black top). The initials BM are not in a custom shop font. There is one lefty who played the tour when this putter was made, and played a Cameron putter most if not all the time, and that's Blaine McCallister.

Condition is 9.8+/10, 35", art of putting HC 

Certificate of Authenticity from Scotty Cameron
