I love these old books. Thanks so much for sharing! Ultimately, I'd love to have a general, every-day kind of hand like this with which I could write letters.
I've started to keep my eye out for ones ever since I recently ran across a large ledger from 1853 in an auction pre-view. It turned out I couldn't make the auction itself, but I did take a quick picture of a page. What I also found a lot of fun was that the original blotter/pen wipe was still in the ledger 150 years later.
Now I wish I had placed a bid, so I'm starting to watch out whenever I can. I've seen some on the famous online auction site but it's a little difficult to get an idea of the quality of the writing sometimes.
Here's a photo I took you might appreciate.
