Remember these? A thingy to pop on the top of your empty milk bottles when you put them out on your doorstep overnight – to indicate how many pints you want delivered in the morning.
The person who invented this took out a patent on it….. and is presumably now either living in a house called Bottlesrest in the Bahamas or (more likely) pushing up the daisies in ‘uddersfield cemetery.
The revolving disc allows you to order from 0 to 6 pints rising in ½ pint in-cream-ents.
In top of the milk coloured purest plastic.
Good working order.
