This is a desktop perpetual calendar made from bright orange plastic.
The large flip-over date is triggered by a small push button on the top; the small, numeric month is controlled by a dial underneath.
The whole housing is angled around 45 degrees mimicking a motorcycle speedometer. It has a great look and a style typical of the 1970s' view of the future.
Who made it and when?
The only identification is "UK Registered No. 977268". We've seen similar items that were made in Hong Kong during the 1980s.
