this is part of an interesting assortment of equipment salvaged from a laboratory.

approximate dimensions: 8-3/16" high (with stopper), 4-3/16" diameter.

there are two small scuffs, visible in my fifth photo. they are not chips, but you can feel them.

the weird photo of the bottom puts the neck of the bottle in the background of Wheaton's Ⓦ glass mark. if you zoom in, you can see the mold number (8).

the photos of the stopper reveal that it wasn't ground evenly. (i hope i am not the only one who prefers the flat-head design.) most of these clear patches feel smooth, i.e. they are typical manufacturing defects. the only one that feels rough is small and near the bottom (last photo).
