In the style of Jungham (founded in 1861) wind up clock, however, I am too warey to pull it apart to find any official markings.

Working Wind up clock which projects a light and time on the ceiling or wall when the original coiled pull chord button is pressed.

Also known as a projector clock, these devices were used where electricity wasn’t always accessible and were commonly used in brothels to notify their clients of their ever fading available time with them.

If you’re the kind that appreciates the rich history of s*x work, this would be a fabulous piece to own. Focus adjustable lens.
