Vitro patch?

Vitro patch? Would this be the "v" patch I have read about?

 I agree .   Other companies have patterns with the V patch. Several Akro and MK have V patterns.  The older Jabo classics can have the V or closed V which has been called the butt crack or a C or S pattern.  This all from a short length glass stream from the furnace to the shear. The glass stream does have time to twist. It just folds over on its self has it piles on the shear blade. It is cut once the piles on the blade space between the two holes and is cut the second time. This V or C or S pattern and usually on one side of the marble is all from the short glass stream length to the shear and the amount of space between the two holes of the shear plate. Most common companies with the V- C or S pattern is Vitro, Cairo, Jabo, later Alleys from St.Marys location. But Akro and MK also have the V, but not the C or S pattern.  Old information and thoughts were that a nice big V meant it was Vitro. That turned out to not be so true. It may be or may not be Vitro.  Some people said that Vitro made the V on purpose to identify the marble with Vitro. That is not true. I knew two Vitro plant managers and both said they never tried to make any V shape.
