Are these Pontil marks ?

I found these 2 broken pieces scratching around at one of my spots. Are the marks on the two bases pontil marks or something else ? I’m kinda new to the pontil stuff and most stuff I find at this spot is late 1890’s to around 1915.

They are not. These are suction scars from early ABM bottles that date towards the 1915 end of your age range.
