Pontil type ID needed.

Pontil identification help please.
I typically don’t have many Pontil based bottles as I live out West. However I have these early Lynch and Clarke mineral waters and don’t know what to call, or how to accurately describe the type of Pontil mark on them. Any help would surely be appreciated. Thanks in advance!

I believe that is typically referred to as a "sand pontil". The following is a great source: https://sha.org/bottle/pontil_scars.htm

That was going to be my guess. Thanks for your input and happy collecting to you!
