Set of 2 Vintage Pyrex Glass Etched Beakers 16oz/8 oz Pharmacy Lab

Description

Set of 2 vintage Pyrex glass etched beakers. 8 ounces and 16 ounces. Both have also been etched with a "W" near top of the measuring area. I do not know what this stands for or if this was done by the previous owner or the manufactured.
The smaller beaker is 8 ounces and stands just over 7.5" tall. The larger beaker is 16 ounces and stands 9.5" tall.
Smaller beaker has a very tiny chip along the edge of base, see next to last picture. Larger beaker has some residue in bottom, likely can be removed with a cleaning brush, which I do not have! See last picture.
Thanks!
