  We extend previous calculations of the zero temperature superfluid fraction
$f_s$ (SFF) {\it vs} localization, from the fcc lattice to the experimentally
realized (for solid $^4$He) hcp and bcc lattices. The superfluid velocity is
assumed to be a one-body function, and dependent only on the local density,
taken to be a sum over sites of gaussians of width $\sigma$. Localization is
defined as $\sigma/d$, with $d$ the nearest-neighbor distance. As expected, for
fcc and bcc lattices the superfluid density tensor is proportional to the unit
tensor. To numerical accuracy of three-places (but no more), the hcp superfluid
density tensor is proportional to the unit tensor. This implies that a larger
spread in data on $f_s$, if measured on pure crystals, is unlikely to be due to
crystal orientation. In addition, to three decimal places (but no more) the
curves of $f_s$ {\it vs} $\sigma/d$ are the same for both the hcp and fcc
cases. An expected value for the localization gives an $f_{s}$ in reasonable
agreement with experiment. The bcc lattice has a similar curve of $f_s$ {\it
vs} $\sigma/d$, but is generally smaller because the lattice is more dilute.
