Lower this torpedo down the well and pull the string attached to the trigger.
A very weathered patent tag, but it has lasted since 1865.
Declared safe by the military at Picatinny Arsenal before being displayed at the Morris Museum in the 1980s.

I think that the major part of this model is lead, and would explode in the well and be lost. The upper portion could be pulled up(a heavy metal bail is attached) and used with a new "charge"
