Got a piece of the above spacer at work but haven't tested it yet, wife came down with Covid on Friday morning so I'm pretty busy taking care of her and things around the house. She is fine and nobody else is positive, so if I get a break today I'll give it the pencil test if nothing else. I've found it just as reliable as using the Lee tester.
Update
It took a H hardness pencil to scribe the lead spacer I have, estimated BHN is 20 to 22.
