Amber Lewis & Towers Practical Poison Bottles

The "practical poison bottle" comes in many sizes and colours.  Blue, green, amber, near black, aqua and clear glass bottles are recorded.  There are lip variations depending on the age of the bottle including: normal, wide-mouth, ones for retaining a glass stopper, a Corbyn type lip and even a rare shear lip version.  Normally the bottles appear with warning hob-nail crosses although more rarely they have warning ribs.  There are also Non-UK versions of this bottle although these are not technically the L&T design.

It has a Patent no. of 334871 dated 6th March 1899.
