or at least offering a different measeured dimension. The below from a study by Reginald Schilke- "Now, recall that all three instruments played identically the same in
brass, or as close as it is possible to get. I had varius players from
the Symphony working with me as well as other professional trumpet
players in Chicago and they agreed unanimously on the results. The
findings were that plating does not affect the playing qualities of brass
instruments. That is, the plated instrument and the plain brass
instrument played identically. The lacquered instrument, however, seemed
to be changed considerably. This instrument, which originally had played
the same as the other two, now had a very much impaired tonal quality and
the over all pitch was changed.

To explain these findings as to why the silver and brass instruments
played alike and the lacquered instrument did not, let me give you some
figuers. The silver plating on a brass instrument is only .0005" thick.
The lacquer that goes on, if it is a good lacquer job, is approximately
007" thick. Now to get an idea in your minds as to what these thickness
figures represent, an ordinary piece of writing paper is approximately
004" thick so the silver that goes on an instrument is only 1/8 as thick
as a piece of writing paper, while lacquer is almost double the thickness
of a piece of writing paper. The silver in itself is very compatible to
the brass. The lacquer, if it is a good lacquer and baked on, will be
almost as hard as glass and not at all compatible to brass. The lacquer
on the bell of an instrument is .007" thick on the outside and another
007" on the inside which gives you a total thickness of .014". This is
already the thickness of the metal of my instruments so the lacquer
process would double the bell thickness. As you can see, it is bound to
affect the playing qaulity of the instrument."

Considerably thicker than you posit and close to in line with Mr Stofer. Of course it makes that Henry guy look all out to lunch.
