When was my colonial clock made

I just recently purchased a colonial grandfather clock.

I was told it was made in the 1920's but would like to know for sure.

I can't find a serial number or model number on it. The only number that I can find is II42 on the back of the case.

The clock is seven feet tall has two brass weights and a brass pendulum with a wooden rod.

It is dark in color with glass in the door.
