Chesshyre has been credited with establishing the probable origins of the common error of using the term "crest" to refer to the whole achievement. He explains that in the 18th century it was common for smaller items, such as spoons and forks, to be engraved with the crest alone, while the full achievement was reserved for larger items such as salvers. For this reason a number of publications appeared from the late 18th century through to the early 20th century which recorded only crests. Chesshyre later successfully lobbied the chief revise editor of "The Times" to include an explanation of the precise meaning of the term "crest" in a new edition of the newspaper's staff manual.
