These are pictures of a Union Monitor
built for 15mm figures.  The hull was
made slightly small for the turret at the
customer's request.  The turret was
made of brass stock.
This is a model of the Bomb Brig Etna
used in the Mexican American War.  I
used plans printed in Howard Chappell's
The American Sailing Navy.  The Etna
did not carry a traditional Mortar but
rather a short 10" shell gun.  I machined
the gun from brass stock and then had
some cast.
