"Robert F. Wuersch, born in Switzerland, moved to Fall Rivers, Massachutes in 1961. He originally crafted Art Enamels on pure copper and fine wood, after which he founded the Wuersch Manufacturing Clock Company. He continued to work, throughout a serious illness, and passed away in 1995".
As you can see, the company was founded sometime after 1961 and Mr. Wuersch died in 1995. The clock in the post is what is commonly called a "Grandmother" clock and most likely has a Hermle movement. The movement may have a date code on the rear plate. Photos of the movement would help and you can also tell us what, if anything, is on the rear of the clock movement. (works).
