Antique and Vintage Mechanical Clocks

_{Tick-Talk Tuesday is about the letters and comments I have received from readers concerning clock issues, challenges faced, a clock you would profiled or advice on your particular clock concern. For those comments and questions that stump even me, I consult within my clock circles for the best possible answer}

This clock was in My grandparent’s home since the 30’s (I think). My dad (he’s 96) seems to recall my grandfather winding the clock every day, but I just want to make sure. Can you tell me anything about the clock? Thanks for any info you can provide.

My reply:

It looks like a Junghans 8-day Westminster chime bracket style clock, made in Germany. If you open up the back door do you see a  trademark on the back of the movement. Take a photo if you can and send it to me. You do not have to take anything apart to see the trademark. Does the gong have a name on it?

Perhaps he wound it every day because it was part of his ritual but it only requires winding once per week.

S. writes back:

Wow! I didn’t see it before!

S. writes back:

How do I see when it was made?

My reply:

The number below the trademark is A20 which means that it was made in the first 6 months of 1920.
