This is an excellent condition Colonial grandmother clock, Model 1688W with movement 122M and dial DC, I think it says.
The clock is about 71” tall and has base about 12” x 14” a small footprint for such clocks.
See photos.
I am the second owner and it’s in incredible condition for its age. I was told it was bought in 1939. I have not researched it further because it’s always worked just fine for me.
