Well Doug , maybe it sounds "Highly Unlikely" but it's a Fact & the Sheet/Block that comes out of the Bins I dig through, have been sitting in there for 30 - 40 years and I literally Wash them off with Dishsoap to get the engrained Dust + Dirt off of them. I've only had 1 source ever for these 2 recipes. The only highly unlikely thing about it was ending up with that source. All one has to do is Look through My Feedback and Verify All the Randall people and Custom builders that Put a Stamp on the Material ~ It Speaks for itself. We coordinate many Rare & Beautiful Randall builds continuously with Great success. Ken
