Manhattan Series II Navy
The Manhattan Navy Series II pistol, like the Series I, can be identified by the
New York address on the barrel. Later Manhattan Navy pistols will not have the
New York address. While the Series I Navy had NO patent date on the cylinder,
the Series II would be the first series to have the 1859 Patent Date around the
circumference of the cylinder between the cylinder stops and the nipples. It is
visible in the photograph below, lower right corner  The butt of the pistol in this
photograph is representative of all Manhattan Navy revolvers carrying serial
numbers above s/n 1000.
