Vintage 1960's Diamond "Pecking" Chicken Hen Alarm Clock Shanghai China

I am selling a Vintage 1960's Diamond "Pecking" Chicken Hen Alarm Clock Shanghai China. It is pre-owned. It stands about 6 1/2" tall. The alarm clock has a chicken on it and it's head bobs up and down as the clock ticks. On the back of the clock it has Shanghai China on it. I wasn't able to get the alarm to work. The clock works, but the key on the back for the alarm doesn't turn. It may have been over turned at some point, but I couldn't get it to trigger.
