Comments above have made me question whether a leather pad could ever be a Parker Brothers factory original.
The letter for this CH Bernard suggests that a leather pad was indeed available (in 1905 at least). I am referring to the next to last sentence in the final paragraph.
Uncommon perhaps, but something involving leather on the pad was available.

Unrelated comment. Restating something I’ve said before. The PGCA discussion board has perhaps the only section selling items on the web where an abundance of information is available for reference.
