Early Boston Three Star and Two Star Cornets
These two Boston cornets were both made around 1880, not long
after the introduction of the Three Star Cornet.  Both have suffered
from long years of use and second rate repairs but are mostly
complete for display and research purposes.  The first is a very early
silver plated Three Star, made before serial numbers were being
engraved on them, with the larger (aprox. .486") bore size and fixed
valve guides rather than the later three point floating guide and .472"
bore, but otherwise the same as
later examples.  It has some extra
decorative engraving around the standard and familiar pattern.  The
second cornet is a Two Star model made of German silver, which
was an option for all Boston instruments at the time. This one has an
early serial number that would indicate that it was made 1882 or
earlier and still has the earlier fixed valve guides.  These two cornets
appear to be the exact same design other than the optional
material/finish and engraving.  The only detectable difference
between the two models is the slightly larger bell taper of the Two
Star cornet, the mouthpipes, tuning assemblies and valve sections
being of the same design.  Both of these cornets are 12 1/2" long
with bell rim diameters 5 1/8" and bores measuring .485".  

I cover the origins of these designs
more thoroughly on other pages.
