Naming Confusion!

Here is a good example of why attribution can be a problem.

This good quality 16 jewel watch is signed by well known makers & retailers Kendal and Dent - Dent made the clock that drives "Big Ben". But the movement is signed DF&C for Dimier Freres et Cie part of a long established Swiss watch making dynasty, but in this case the movement was actually made by Review Thommen, probably for the London branch of Dimier who were major watch importers.
