Carl and others,
It is not a guess any longer. There were no Armstrong rifles in the batteries. There was only one breech-loader there, a 3 inch Clay rifled cannon. Those lead sheathed projectiles are not Armstrongs, but Clay shells. The rifle was an invention of William Clay of England. At least two Clay rifles were known to be sold to the South.
These guns were also sold to Peru in its 1860s armament. However, the shells sold to Peru are made slightly different in that in addition to the lead sheath there was three lead bands incorporated. I have PDF and Word documents to support my comments if any are interested just email me, they are too large for the Forum.
Will someone tell me who is in possession of the Clay shell recovered at Dutch Gap and which battery may have fired it and how I may contact the owner?
Best Regards,
John
