This is what all us Baby-Boomers had shoved in our face at every event and family function before the day of the Video Camera. It was a Brownie wind-up 8 mm movie camera. You wound it up and a timer on the side told you approx how many minutes of film you had left to shoot.
This is from about 1961...It still works!
Oh...Do you like that fine imported Meakin China in the background?..hehehe Thats a very interesting story on how I obtained that...Another Time.
