Wow, it wounds like you’re well on your way making good progress. I was just thinking, though don’t know if this is an acceptable practice or if it is ok in a historical context, do you know if anyone ever does “pencil rubbings” of the grave stone engravings? Where they hold a piece of paper over the etched parts, and rub a pencil over the paper that then shades in the paper where writing is under it?
Excellent news! That will be exciting. I can imagine walking through historical areas with an app, hunting for history
