Movin On Estate Sales

Very nice clock in VG used condition! Traveling from where I purchased it to my home I got to hear the quarter-hour chimes & the full song on the hour! Beautiful! It has a key, & the sticker on the door indicates it was repaired at one time in San Diego. I tried to wind it or change the time (not familiar with either) & the key worked hard so I didn’t push it. I’ll bet it would run great or someone who knows what they’re doing! Serial # under DRGM is 989568.
