Antique Seitz Brothers Cobalt Blue Beer Bottle For Sale

I have a nice collection of Seitz Brewery Items that I will be listing in the next few days. Items include trays, glass bottles, etc.
Not an expert in this category so please use photos to judge condition. If you have questions please ask.
This is an early mid 1800s bottle I believe.
Approx. 7\" high.
This one has an interesting (to me) \"sworl\" running through it. Not a crack it is in the glass.
I overexposed the photos a bit to capture detail. In person it is a bit darker in color.
