Peel & Stick TPO Corners?

Does anyone know what the manufacturer of this membrane is?

The corner is a peel & stick TPO, definitely not welded down. Date stamp is 12/2006. Pipe boot on this roof is also P/S and date stamp is 04/2007. I have seen P/S pipe boots, but never a corner before and cannot find any info on this.

Good luck to ya. This forum is DEAD! Once a lively fun informative discussion group of know it all and know nothings. Vicky tried her best to keep it safe. ⚰️D.O.A.

Looks like Firestone to me. We had that peel and stick product up here in Canada.  Never really liked it however. Nothing but issues.
