Adolphus Busch Glass Manufacturing and American Bottle Company Blown Aqua Bottles.

All of the following bottles look like beer bottles to me.  The first four are Adolphus Busch bottles.  All of those are aqua and show some nice bubbles in the glass.

From the maker's marks on the bottoms, I can tell that the first four are from an Adolphus Busch glass plant, while the others are from the American Bottle Company, which made bottles for Busch after the Busch glass plant burned down. 

 

Four Aqua Adolphus Busch A B G M Co Bottles.

Of the Adolphus Busch bottles, only the third (most right above) bottle has a crown top.

Going left to right, the bottoms are embossed as follows. 

A. B. G. M. CO. in an arc with K86. 

A. B. G. M. C.  Not listed in SHA) full circle and larger letters than the first.  J in the middle.

A. B. G. M. CO.  straight across - not in an arc.  K23 below.  

All three of those would be from the 1892 - 1916 period according to the SHA.org site.

Crown bottle tops were invented in 1892 in England and were relatively rare for Busch bottles.  They were sometimes corked too.

Here is a great study on Busch bottles.  AdolphusBusch.pdf (sha.org)

Below is one older Busch Glass Co. bottle (far left) and three American Bottle Co. bottles.

Old Aqua Adolphus Busch Bottle (left) and 3 Crown Top American Bottle Co Bottles.

The Adolphus Busch bottle would be the oldest and is embossed on the bottom A. B. G. Co. straight across with an 8 below.  The G is indistinguishable from C.  The periods are very faint.  The age range of that bottle would be 1886 - 1892.   There is a very distinct line showing where the applied lip was applied to the neck of that bottle.

The other three bottles were made by the American Bottle Company.

Those three bottles have maker's marks as follows (left to right).

A. B. Co.  straight across with A 30 below. 

A. B. Co. same as above but F25 below.  

A B Co across without periods.  41 below.  This one, without periods, is not listed in SHA.org sitem but maybe the periods are just very faint.

From SHA.org, here are those marks.
