'Two fingers o' whisky, Frankie!'

A very interesting pewter piece, hosting a gun-like hand gesture, which suggests 'two fingers' as a common measurement of whisky.
Lightly engraved are the words 'Norfolk Constabulary Bowls Tour 1985'. 
Very interesting for those who collect police related curiosities, but barely noticeable for those who don't, being on the back of the piece.
