No it isn't. Actually we are both wrong because the name Clevite was
not coined until 1952 which was when the Cleveland Graphite Bronze
Corporation and the Brush Development Company merged. So it was just
Brush when that microphone was made. But after 1952 the company name
and trademark was "Clevite Brush" in that order. Below are a "few"
sentences cut and pasted from all sorts of items about the company,
company execs, and the company's products.
