An interesting piece of kitchenalia. Still in working condition. I have wound it up to the 15min mark and it works as long as its kept in an upright position, so I cant guarantee it will continue to do this as its probably about 80 years old!!!. At the end of 15 mins a short brrr rings to signal time is up. I am not 100% sure but from a little research it appears to be from a 1940’s stove although I stand for correction. Someone has made a box for it which works well for standing up / displaying in. It appears to be cream enamel under the white paint and would probably look good cleaned off. The clock face is also enamel and in good condition.
