Building "X" stood very close to the Monocacy Creek, just west of the lower of the two bridges that crossed the Creek. (This road is now Christians Spring Road.) Building "X" has been identified as the Gunstocking Shop. But its configuration of doors and windows do not match a plan of a gunshop, which seems to be that of the Christiansbrunn gunshop. All depictions of Building "X" show a copse of trees between it and the Creek.
The image below locates the Building "X" on a 1795 map of the Christiansbrunn community.
