I called the clock owner back and indicated that the correct spelling on the clock itself is:
M-U-S-C-H-E-L
However, when I try to Google Muschel, I'm not getting much on clock manufacturers or clocks for that matter.
Perhaps I will have to take a picture of the clock and post it for folks to see.
Picture of the Clock by: Bill
Yes, a picture may help someone identify your clock. You can post it here in a new post along with the manufacturers name, and I will transfer the picture to this page.
