Scott,
No, the one the Army moved from Ft. Mcnair to NYC had been in the same spot since received early in the CW. Photos exist showing the rows of heavy arty there in cw incl the 13 in. Mortars. I inspected it and there was no evidence it had fires as vent was must same cond as the 3 others there then.
One distinctive feature of the one in the photo is a chip out of the bore just at the muzzle ;face which could be compared to the one at Hartford. A ladder is needed to see the muzzle of/the Hartford item.
