Filling your glass with a old optic is a treat. When the optic glass is filled by turning the lever it looks like you got a huge shot of whisky.

 

Surprise

The optic is a thick magnifying glass that gives you the impression that you got a lot of boose for your money. Content 1/6 gill (23.7 ml) or 1/5 gill (28.4 ml).
