Note: This movement is a model 1877. Note that the

are either Hunting case configuration or key wind
with the pivots in a hunting case configuration.
The odd thing about this run is that the balance
wheel is adjusted and has a gold balance screw at
the end of the balance wheel arm. This appears to
be the only Broadway run that has an adjusted
balance wheel and was both visually confirmed and
