The rose wood case is typical for c.
1850's instrument cases. The brass banded corners and reinforcements
are also typical of the 1850's. The swinging latches are more typical of an earlier
period, and especially of sets produced in England. The style of the
trephine crown is pre-1860, but later than the vertical 'escape' style seen
in the earlier example from this maker.
