Dear members, thanks for the replies.
Chipster, you are correct. I began collecting the old baseball gloves because their leather was old, soft and supple. Some were turned into watch straps and cases. But those hanging in my current shop were a bit too nice, plus I have read that some were stuffed with asbestos.
I still use newer gloves but the leather is not as nice, still, I made one for a friend’s Seiko years ago and it is still his favorite (bottom photo).
