This gun is displayed in Hagerstown Maryland.
It was reciently un-earthed in a garden and put on display.
The story goes it was cast for the revolution in those hills with 77 other tubes but the core was off location.
This one still has the sink head on with the off center core.
Sounds like the night shift scraped another but just hid it in the weeds
to save their butts.
This shows that cannon were cast vertically in at least some foundries.
