Charles Kandler
Charles Kandler's life and career are certainly an enigma. It has been suggested by several commentators that there were in fact two or three Kandlers, owing to the fact that a variety of marks were listed sequentially under the names of;
Charles Kandler (active 1727-1750) - Charles Frederick Chandler (I)
Frederick Kandler (active 1739 until 1776) - Charles Frederick Chandler (II)
Charles Frederick Kandler (active 1775-1793) - Charles Frederick Chandler (III)
Moreover, all three of these names were registered at the same address at St. James's continuously from 1735 to 1793. It is possible, and indeed likely, that the marks were used by at least 3 goldsmiths, perhaps a father, son (or nephew) and grandson.
