I purchased a Lawrence holster last weekend at the Reno, Nv. gunshow. It is marked 120B, logo underneath, and 601 below logo. This holster is basketweave and looks very close to new. I couldn't pass it up. I believe it is for a SAA with six inch barrel or longer. I have absolutely no need for the holster, but this forum has given me some sort of disease that compels me to buy such things.
