Query: Topflavor: A Separate SU(2) for the Third Family   We consider an extended electroweak gauge group: SU(2)$_1 \times$ SU(2)$_2
\times$ U(1)$_Y$ where the first and second generation of fermions couple to
SU(2)$_1$ and the third generation couples to SU(2)$_2$. Bounds based on heavy
gauge boson searches and current precision electroweak measurements are placed
on the masses of the new heavy gauge bosons. In particular we find that the
mass of the heavy W boson can not be less than 800 GeV. For some range of the
allowed parameter space, these heavy gauge bosons produce observable signals at
the Tevatron and LEP-II.
