Distillery workers in the early/mid 20th century developed a simple device called a "dog" to steal small amounts of whisky.
These dogs turn up occasionally and here is a typical example made of an old copper tube sealed at one end and corked at the other.
The worker would fill the dog at the end of his shift by dipping it into a full barrel, corking it and then hanging it onto his belt underneath his trousers, all out of sight of the exciseman.
Beside the copper tube dogs, there were other varieties from slim bottles to body-shaped flasks.
Over a year a worker could steal the equivalent of about 80 bottles of whisky...more if he went home at lunchtime.
Antiques and collectables.
