That's some great stuff! The Stone with 3 different angles explains why so few of the ones I have with the mark up to the right match up.
I've been trying to figure out what happened. One thought is that the scratch was deliberate maybe to mark the stone for resurfacing. I think that's unlikely now.
The other thought was that there was a bit of stone or other debris when another was slid on top of it in storage. Schulte has a scratch that seems the sort of zig zag you'd get from that.
