Please post back any additional details you find about this new PC leather. I've traded a few emails with casedawg and am considering ordering a BV1929 made from this leather for my daughter. There is not much about it online when I search so if you've learned anything from your research please share.
Case said that PC is steerhide. Said that it is inbetween the 22 steerhide series and the limited Kip. Said he really likes it.
SO, I am not familiar with the Vinci gloves first hand. Are they a "high end" glove? May be looking soon
