Wow...
First off, NWA 5363 HAS been confirmed paired, as well as 6292 and yours.

I think YOU should check your facts before calling me out like you are.
A simple search of the metbul shows the REPORTED TKW of the material and simple math will show you the TKW of material that is in the 5363/5400/6077/6292 pairing group.

Please do not publicly accuse me of things when YOU are the one who is not up to date with information and you do not have the facts correct.

I have no interests in this material other then as a collector. I am not selling any of the material from any pairings.

Why do you feel the need to come at me like you did? There is a nice amount of this available.

I expect an apology for your comments as you are out of line and clearly in the wrong.
ALL I STATED IS FACTS.
