Vintage Electric United Clock Corp

Vintage Electric United Clock Corp. This is an awesome piece from 1969 as you can see in pics the date was etched into the back of the clock (I’m not sure if that was standard practice back then) or if my father in law did it. It also has the number 1000 etched as well. The keeps fine time, I had it plugged in for a full day. This had been in their shed along with many other items which I’ll be posting over “time” lol. It will need a good cleaning. I didn’t want to attempt as I was afraid I might ruin it. Measures 8” tall **please see pic of the number 5 on the clock face, there appears to be a few small specs of black debris.
