A weird ball bottle??

[KentuckyBotryoidal]

All markings on the bottle are:

PAT 98735

4

Ball

Then on one side near the bottom: 88016

I was just wondering what it was used for? I've never seen a ball mark on a bottle like this. Thanks!

ball glass made all kinds of bottles at one time. this one looks to be a cough medicine , from the late 1930s .
